what is a bibliographic essay

Bibliographic Essay Guidelines

General Information

Choice bibliographic essays are intended to identify core books, journals, and digital resources that meet the needs of undergraduates, faculty, and librarians serving these users. Essays address new curricular or interdisciplinary areas; subjects that have garnered significant recent interest; or important new literature on a traditional subject. When the subject and due date of the essay are agreed on, the editor will send the author a copyright agreement to sign and return (by mail or as a scanned PDF file).

Essays are not introductions to a topic, but rather informative discussions of important literature on a topic. Accordingly, essays * take a position * in subjectively selecting and discussing the most important resources for the topic. The author's point of view sets the framework for the essay and provides its raison d’être. Rather than listing and describing resources, the author should evaluate each of the titles in a way that proves its worth to the body of literature about the topic and, thus, why it is in the essay. The author should also discuss the relationships between the resources discussed, providing a narrative thread throughout that explains how the resources are the same or different; if/how one picks up where another leaves off; how changes over time and/or historical context impact the research; and how the titles relate and create a well-defined body of work about the topic. Seminal works should be identified as such; particular journal articles should be included only if they are essential to the topic.

Organization, Length & Format

Essays should begin with an introduction and conclude with one or two summary paragraphs. The introduction should set the stage by describing the topic and the general state of the scholarly literature supporting it. It should also describe the characteristics of the body of selected resources, presenting a brief “thesis”—explaining the selection and why it succeeds as a core literature for that particular field of study. The introduction should then briefly describe the organization of the essay and explain the reason for that organization. The text should be prepared in MS Word with minimal to no formatting (Word templates should not be used). Reference materials—bibliographies, dictionaries, etc.—are typically discussed together, as are digital resources. But this is not a hard rule. Essays should discuss 50-75 titles and should top out at about 5,000 words. (Sample essays are available at http://ala-choice.libguides.com/ .)

Editing & Style

Essays are edited for clarity and Choice house style. The editor will send the author a copy of the edited essay, with queries and comments, if any, before the essay goes to the copy editor. The editor will send the author page proofs before the essay goes to production.

Works Cited

Every title mentioned in the essay should be in the works cited list, and all titles in the works cited should be discussed in the essay. Citations should be arranged alphabetically by author (or by title, for edited works and digital resources). Information should include author(s)/editor(s), title, publisher, date of original publication, and (if applicable) preferred edition. URLs for internet resources should be formatted without embedded hyperlinks.

How To Write a Bibliography (Plus Printable Guide With Examples)

Give credit where credit is due.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

Plus grab our printable Bibliography Guide for Students with examples from all three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . Just fill out the form on this page to get the free guide.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

• Books and e-books
• Periodicals like magazines or newspapers
• Online articles or websites
• Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography to show all the works you used in researching your paper. This can help the reader see that your points are well supported and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text that are woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order and may include: ADVERTISEMENT

• Author/s or creator/s
• Publication date
• Volume and issue numbers
• Publisher and publication city
• Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list to only items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

• Title your bibliography section “References” and center the title on the top line of the page.
• Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
• Include all types of resources in the same list.
• Alphabetize your list by author or creator, last name first.
• Do not spell out the author/creator’s first or middle name—only use their initials.
• If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
• Place the date in parentheses.
• Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
• Italicize the titles of books, periodicals, and videos.
• For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books):

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized (unless there’s a proper name/noun) . Publisher. Publisher’s website

• Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical APA Bibliography Examples

For journal or magazine articles, use the following format. If you viewed the article online, include the URL at the end of the citation.

Last Name, First Initial. Middle Initial. (Publication date). Title of article. Magazine or Journal Title (Volume number) Issue number, page numbers. URL

• Bell, A. (2009). Landscapes of fear: Wartime London, 1939–1945. Journal of British Studies (48) 1, 153–175. https://www.jstor.org/stable/25482966

APA Bibliography (Reference List) Example Pages

MLA Style Bibliography Examples

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

• Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
• Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
• Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
• Alphabetize your sources using the first word of the citation, usually the author’s last name.
• Include the author’s full name as listed, last name first.
• Capitalize titles using the standard MLA format.
• Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use the following format. Add the URL at the end for e-books.

Last Name, First Name Middle Name. Title . Publisher, Date. URL

How to Write a Bibliography in APA Format

• APA Bibliography
• How to Create One
• Why You Need It

Sample Bibliography

An APA format bibliography lists all of the sources that might be used in a paper. A bibliography can be a great tool to help you keep track of information during the research and writing process. In some cases, your instructor may require you to include a bibliography as part of your assignment.

At a Glance

A well-written APA format bibliography can help you keep track of information and sources as you research and write your psychology paper. To create a bibliography, gather up all of the sources that you might use in your paper. Create an APA format reference for each source and then write a brief annotation. Your annotation should be a brief summary of what each reference is about. You can quickly refer to these annotations When writing your paper and determine which to include.

What Is an APA Format Bibliography?

An APA format bibliography is an alphabetical listing of all sources that might be used to write an academic paper, essay, article, or research paper—particularly work that is covering psychology or psychology-related topics. APA format is the official style of the American Psychological Association (APA). This format is used by many psychology professors, students, and researchers.

Even if it is not a required part of your assignment, writing a bibliography can help you keep track of your sources and make it much easier to create your final reference page in proper APA format.

Creating an APA Bibliography

A bibliography is similar in many ways to a reference section , but there are some important differences. While a reference section includes every source that was actually used in your paper, a bibliography may include sources that you considered using but may have dismissed because they were irrelevant or outdated.

Bibliographies can be a great way to keep track of information you might want to use in your paper and to organize the information that you find in different sources. The following are four steps you can follow to create your APA format bibliography.

Start on a New Page

Your working bibliography should be kept separate from the rest of your paper. Start it on a new page, with the title "Bibliography" centered at the top and in bold text. Some people use the title "References" instead, so it's best to check with your professor or instructor about which they prefer you to use.

Gather Your Sources

Compile all the sources you might possibly use in your paper. While you might not use all of these sources in your paper, having a complete list will make it easier later on when you prepare your reference section.

Gathering your sources can be particularly helpful when outlining and writing your paper.

By quickly glancing through your working bibliography, you will be able to get a better idea of which sources will be the most appropriate to support your thesis and main points.

Reference Each Source

Your references should be listed alphabetically by the author’s last name, and they should be double-spaced. The first line of each reference should be flush left, while each additional line of a single reference should be a few spaces to the right of the left margin, which is known as a hanging indent.

The format of each source is as follows for academic journals:

• Last name of first author (followed by their first initial)
• The year the source was published in parentheses
• The title of the source
• The journal that published the source (in italics)
• The volume number, if applicable (in italics)
• The issue number, if applicable
• Page numbers (in parentheses)
• The URL or "doi" in lowercase letters followed by a colon and the doi number, if applicable

The following examples are scholarly articles in academic journals, cited in APA format:

• Kulacaoglu, F., & Kose, S. (2018). Borderline personality disorder (BPD): In the midst of vulnerability, chaos, and awe.  Brain sciences ,  8 (11), 201. doi:10.3390/brainsci8110201
• Cattane, N., Rossi, R., & Lanfredi, M. (2017). Borderline personality disorder and childhood trauma: exploring the affected biological systems and mechanisms.  BMC Psychiatry,   18 (221). doi:10.1186/s12888-017-1383-2

Visit the American Psychological Association's website for more information on citing other types of sources including online media, audiovisual media, and more.

Create an Annotation for Each Source

Normally a bibliography contains only references' information, but in some cases you might decide to create an annotated bibliography. An annotation is a summary or evaluation of the source.

An annotation is a brief description of approximately 150 words describing the information in the source, your evaluation of its credibility, and how it pertains to your topic. Writing one of these for each piece of research will make your writing process faster and easier.

This step helpful in determining which sources to ultimately use in your paper. Your instructor may also require it as part of the assignment so they can assess your thought process and understanding of your topic.

Reasons to Write a Bibliography

One of the biggest reasons to create an APA format bibliography is simply to make the research and writing process easier.

If you do not have a comprehensive list of all of your references, you might find yourself scrambling to figure out where you found certain bits of information that you included in your paper.

A bibliography is also an important tool that your readers can use to access your sources.

While writing an annotated bibliography might not be required for your assignment, it can be a very useful step. The process of writing an annotation helps you learn more about your topic, develop a deeper understanding of the subject, and become better at evaluating various sources of information.

The following is an example of an APA format bibliography by the website EasyBib:

There are many online resources that demonstrate different formats of bibliographies, including the American Psychological Association website . Purdue University's Online Writing Lab also has examples of formatting an APA format bibliography.

Check out this video on their YouTube channel which provides detailed instructions on formatting an APA style bibliography in Microsoft Word.

You can check out the Purdue site for more information on writing an annotated APA bibliography as well.

What This Means For You

If you are taking a psychology class, you may be asked to create a bibliography as part of the research paper writing process. Even if your instructor does not expressly require a bibliography, creating one can be a helpful way to help structure your research and make the writing process more manageable.

For psychology majors , it can be helpful to save any bibliographies you have written throughout your studies so that you can refer back to them later when studying for exams or writing papers for other psychology courses.

Bibliographic Essay Writing from A to Z

When you get a bibliographic essay as a writing assignment, what do you usually feel? If you feel confused, this rather can be understood. It is clear with the writing of some other kind of essay, but a writing a bibliographic essay… What is it, by the way?

What Is a Bibliographic Essay: Definition and Structure

So, what is a bibliographic essay? Do you know by the way such word as “bibliography”? If yes, then, you can already guess what can be the content of such an essay. Yep, a bibliographic essay is an essay about literary sources to a particular topic. So, if you are looking for materials for some paper, a good tip would be to find a bibliographic essay on this topic. There, you can find information about many sources.

The primary task of such an essay is not to provide a discussion of a particular topic. When you are working on an annotated bibliographic essay, your main task is to find a reputable source on some topic. But it is not enough just to find those sources. You should discuss them, compare them, and recommend those, that, in your opinion, are the most reliable.

Related essays:

• Journal Writing In The Curriculum essay
• I have Changed essay
• Independent/Alternative Media vs. Mainstream Media essay
• When there is a war essay

In a critical bibliographic essay, you might need to discuss the sources and compare them rather than just provide some information about them. But even in such case, you should base your statements not on your opinion, but on generally accepted ideas and opinions.

How to Write a Bibliographic Essay Correctly

So, how to write a bibliographic essay? Are its structure and writing principles the same as in the case with any other essay? How to avoid the mess and write a proper paper that will get a good grade and will be useful?

Select Only Reliable Sources

For your essay, you should find only those sources that are recommended for schools. Don’t use encyclopedias, as they provide shortened and incomplete information. Website publications are in most cases not verified and unreliable. You can use only those publications that appear in reputable journals and provide relevant and reliable information.

What about your school library by the way? There are many online and offline sources, but the principles are the same for all of them: reliability and trustworthiness. Once you have found such a source, include it in your essay without any hesitations.

No Analyzes or Discussion

Don’t forget that your essay has a target to give your reader an idea of which sources to use. You don’t have to discuss them, to try proving that your opinion is right and so on. Leave these methods for other kinds of papers, and your task is different now.

Your primary task is to give a summary of those thoughts and ideas that others have written. Don’t express your judgments about those opinions. Your task is to provide information, without discussing who is right and who is wrong and with whom you agree or disagree.

Bibliographic Essay Format Differs from a Usual Writing

Yes, a bibliographic essay format is quite different than anything you can expect. What can we compare it with? Well, maybe, a bibliography would be the right comparison. But in your essay, you give not only the source data but also information about its content.

You might want to write about the authors of those sources, who they are, why they are significant, and so on. If it is available, mention their background in the field, their other relevant works. Everything would work, any objective information about the source and its author.

Yes, this might surprise you, but the sources should be numbered. Yes, like any bibliography. The purpose is just to make it easy for your reader to find a needed source. There are such writing styles as APA, MLA, Chicago – you can use any of them or the one that is required by your school.

Bibliographic Essay Topics Are Very Diverse

Basically, you can write your essay on any topic. Bibliographic essay topics are limited only by your knowledge and imagination. Do you need some examples? Okay, here are some:

• Concentration camps.
• Justice and how it can be perceived.
• Children with neurological diversities.
• Elections and transparency.
• Phenomena of plagiarism.

Any topic that is discussed nowadays is okay. Just a small suggestion: don’t select those topics that aren’t interesting to anybody. Too specific or too old-fashioned topics are just not the perfect fit. Did you get it? By the way, what about selecting some topics about the school where you study? Moreover, your teacher can help you to choose a theme that he is expecting from you.

When you write a bibliographic essay, you might face a number of difficulties. First of all, this kind of essay is not so easy. Second, it requires much attention to details. That is why we are glad to offer you our help whenever you need it. If you have just started writing and noticed, that you are not managing it correctly, you can always place your order and buy your essay from us.

What is a bibliography?

A bibliography is more simple than it sounds. It is a list, usually at the end of an undergraduate or master's dissertation , of all the sources you have used to help you write the essay. This includes both the sources you may have referred to or quoted already in the essay and also any further works you read whilst preparing or researching the essay, even if you didn’t specifically cite them.

Using a separate line for each new text listed, simply write out the details of each of your texts in the following order: Author (surname, initials), year of publication, title of book (in italics or underlined), edition (if there have been more than one), publisher, place of publication. For example:

Jones, AK, 2004, The Artists of Antiquity , 2nd edition, Virago, London

Writing a bibliography: primary and secondary sources

If you are writing a dissertation on a particular author or poet, you may want (or be required) to divide your bibliography into primary and secondary sources. In this case, works by the author himself that have formed the basis of the texts you have studied are primary sources, whilst critical reference books or other material are secondary sources. For example, in a dissertation on Austen, Pride and Prejudice would be a primary source, whilst Austen’s narrative voice: A companion would be a secondary source.

Bibliography styles: Harvard and others

There are several different accepted styles of bibliography, which have slight variations on the information included and the order in which it is presented . The method described above is a standard, widely accepted format, but when you are writing a bibliography make sure you check exactly what stylistic requirements are stipulated by the University or course provider. Remember, one of the most important tips on how to write a bibliography is to remain consistent – whatever method you choose, stick to it throughout and keep the style the same for every reference.

How to write a bibliography

Published March 26, 2021. Updated June 2, 2022.

Bibliography definition

A bibliography is defined as a list of sources written on a particular subject or by a specific author.

Overview of how to write a bibliography

All sources should be appropriately cited both within the text and in the references. The word “bibliography” refers both to reference lists in general and to a list specific to Chicago/Turabian style. Depending on the discipline and paper guidelines, it should be formatted in MLA, APA, or Chicago/Turabian style. An online tool or an official style guide can be used to properly cite the references.

Worried about your writing? Submit your paper for a Chegg Writing essay check , or for an Expert Check proofreading . Both can help you find and fix potential writing issues.

Pick the right citation style

There are three main styles for formatting your essay: MLA, APA, and Chicago/Turabian. Your choice will depend on your teacher, assignment, or discipline. For student papers, consult your teacher or department if you are unsure which to use. If submitting to an academic journal, you should check the guidelines for submission.

Bibliography v. Works Cited v. References

“Bibliography” is both the generic term for a list of sources and the term for the Chicago/Turabian end citations.

The main difference between the two is that a Chicago bibliography lists all works used in writing the paper, both works cited and works consulted. On the other hand, MLA and APA use reference lists instead of bibliographies, which only list works directly cited within the body of the paper. An MLA reference list is headed “Works Cited.” An APA list is headed “References.”

Resources available

When crafting your bibliography, use a manual or style guide. Even if you’ve memorized the basic formatting and most common entries, you may want to look up the format for less common source types.

Naming authors in MLA citations

If there is only one author, write the full name: Last name, First name. If there are two authors, list them in the order they appear on the book cover with only the first inverted. If there are three or more authors, list only the first, followed by the Latin phrase “et al.”

Book citation

In general, an MLA citation for a book follows this format:

Last Name, First Name. Book Title . Publisher City*, Publisher, Publication Year.

Norgren, Jill. Belva Lockwood: The Woman Who Would Be President . New York University Press, 2008.

*Note the absence of the city of publication. In MLA style, only include it to differentiate between a publisher’s different offices or if the book was published before 1900.

Article citation

In general, an MLA citation for a periodical follows this format:

Author(s). “Article Title.” Periodical Name , Publication date, pages.

If you found the article online or in an online database, you will need to include that information. Use the DOI number if available. If you cannot find it, use a stable URL.

You should also cite the volume and issue number if applicable.

Grossberg, Michael. “Who Gets the Child? Custody, Guardianship, and the Rise of a Judicial Patriarchy in Nineteenth-Century America.” Feminist Studies , vol. 9, no. 2, 1983, pp. 235–260. JSTOR , www.jstor.org/stable/3177489.

Because the amount and type of information available can vary so dramatically, the citations for websites can also look quite different from one another. The basic format is

Author (if known). “Webpage Name.”  Website Name . Publisher, Date published (if known), URL or DOI, Date accessed (if applicable).

The following citation is for a blog entry on the Women at the Center website published by the New York Historical Society and Library:

Mogulescu, Laura. “Eliza Webster’s Seneca Village and 19th-Century Black Life in NYC.” Women at the Center , New York Historical Society Museum & Library, 17 Feb. 2021, womenatthecenter.nyhistory.org/eliza-websters-seneca-village-and-19th-century-black-life-in-nyc/.

Sample Works Cited page

The following provides an example of an MLA reference list with several different kinds of entries.

—. Rebels at the Bar: The Fascinating, Forgotten Stories of America’s First Women Lawyers . New York University Press, 2016.

APA style is the second most commonly used citation style for student papers and the most used in academic publishing.

An APA reference list accompanies a paper with in-line parenthetical citations. Unlike MLA, APA cites the date of the source rather than the page of the material referenced: (Author, date).

The general formatting for an APA reference page resembles an MLA Works Cited page.

Naming and alphabetizing authors in APA citations

Write each author’s last name, as well as their first and middle initial. Unlike in MLA citations, list all authors up to (and including) twenty. If there are more than twenty authors, use an ellipsis after the first nineteen and end with the final author.

Alphabetize reference entries by the author’s last name. However, if there is more than one work by the same author, arrange those entries chronologically, beginning with the oldest and ending with the most recent.

Capitalizing titles

Instead of using title case, only capitalize proper nouns, the first word of the title, and the first word after a colon and a dash if applicable.

APA distinguishes between academic journals and other kinds of sources. Because of this, journal titles are the only exception to the above rule. Capitalize all major words.

The general APA format for citing a book is

Last Name, First Initial. Middle Initial. (Publication Year). Book title . Publisher.  

Norgren, J. (2008). Belva Lockwood: The woman who would be president . New York University Press.

Scholarly journal article citation

The general APA format for citing an article in a journal is

Last Name, First Initial. Middle Initial. (Publication Year). Article title. Journal Name, volume (issue), pages. DOI or URL

Use the DOI number if available. If you cannot find it, use a stable URL

Grossberg, M. (1983). Who gets the child? Custody, guardianship, and the rise of a judicial patriarchy in nineteenth-century America. Feminist Studies , 9 (2), 235–260. https://www.jstor.org/stable/3177489

Website citation

The general APA format for citing a website is

Last Name, First Initial. Middle Initial. (Year, Month Date).  Webpage title . Website name. URL.

Chicago/Turabian Style

Chicago style is most commonly used for published works. Turabian style is a modified version of Chicago style for higher-level student papers.

Chicago-style papers can either use a parenthetical citation that greatly resembles APA style citation, or they can use foot or endnotes and a bibliography.

A Chicago bibliography often lists works consulted, as well as works cited.

Begin on a new page after the last page of your essay. Keep the same one-inch margins, header, and page number format as the rest of the text.

Unlike MLA and APA reference lists, the entries have half-inch hanging indents but are single-spaced. Leave an extra line between entries.

At the top of the page, center the word “Bibliography” (not in quotation marks). Leave two lines between this heading and your first entry.

Naming authors in Chicago citations

In footnotes, cite up to three. Use “et al.” if there are more than three. In the bibliography, list up to ten authors.

If you list more than one work by the same author, only write out the author’s name for the first one. Thereafter, use three m-dashes: —.

The basic Chicago format for a book is

Last name, First name.  Title . Place of publication: Publisher, Year of publication.

Unlike in MLA style, provide the place of publication for all entries.

Norgren, Jill. Belva Lockwood: The Woman Who Would Be President . New York: New York University Press, 2008.

Scholarly Journal Article citation

The basic Chicago format for an article is

Last name, First name. “Article title.” Journal Name Volume, Issue (Publication date): pages. DOI or URL.

Grossberg, Michael. “Who Gets the Child? Custody, Guardianship, and the Rise of a Judicial Patriarchy in Nineteenth-Century America.” Feminist Studies 9, no. 2 (1983): 235–60. https://www.jstor.org/stable/3177489.

The basic Chicago format for webpage citation is

Last Name, First Name. “Webpage title.” Website Name. Publisher Publication or revision date. Access date if no other date is available. URL.

Mogulescu, Laura. “Eliza Webster’s Seneca Village and 19th-Century Black Life in NYC.” Women at the Center. New York Historical Society Museum & Library, February 17, 2021. https://womenatthecenter.nyhistory.org/eliza-websters-seneca-village-and-19th-century-black-life-in-nyc/.

Bibliographic research

The search and collection of information from published sources (books, journals, newspapers, etc.) nowadays may include other types of documents, such as websites, reports from bibliographic databases, etc.

Searching for bibliographic sources relevant to your project is an integral and unavoidable part of the thesis work.

To find out how to conduct your bibliographic research, we suggest you consult the Bibliographic Research Guide .

For a start, you can consult the Library books on academic writing (how to write assignments, presentations, theses ...):

Literature review

Literature review is the analysis of the academic literature (articles, books, dissertations, theses, etc.) that you have identified when performing your search on the topic.

A review of the relevant literature for the topic selected is a key element of any academic project (dissertation or PhD thesis, writing an article for an academic journal…) for several reasons:

• it provides you with the conceptual context for your research

• it allows you to acquire, deepen and organize knowledge in the chosen research area

• helps you define or better focus your research objectives

Furthermore, its objectives are:

• describing the state-of-the-art on the given subject (what is the knowledge achieved so far in the research area in which your project fits?)
• identifying strengths and weaknesses, potential gaps in the current knowledge, unexplored empirical issues, or issues that need to be updated
• understanding how the research question is positioned within the field (to what extent does your work provide an original contribution to the research context?)

Creating an MLA Bibliography

If you write a research paper in MLA format, then you will need to include a Works Cited page according to the current 9th edition of the Modern Language Association (MLA) guidelines. Along with citing your sources within the body of your paper, you also need to include full citations of all sources at the end of your paper. The references in a bibliography are formatted in the same way as they would be in a Works Cited page. However, a bibliography refers to all works that you have consulted in your research, even if you did not use their information directly in your paper.

When you use the correct MLA bibliography format, it shows the reader what sources you consulted, makes finding your sources easier for the reader, and gives credibility to your work as a researcher and writer. This MLA sample paper will show you how the bibliography is incorporated into the rest of your paper. We also have a guide on APA reference pages , if you are following APA style in your paper.

Works cited or bibliography?

You may be wondering, what is a bibliography, and how is it different from a Works Cited page? The difference between the two is that while a bibliography refers to any source you consulted to write your research paper, a Works Cited page only includes full citations of the sources you quoted or paraphrased within your paper.

Typically, when someone says, “MLA bibliography” they really mean a Works Cited page, since the MLA format usually uses a Works Cited page instead of a bibliography.

A bibliography in MLA format may also refer to a Works Consulted page. If you used other sources that you did not directly quote or paraphrase within the paper, you will need to create a Works Consulted/Additional Resources page. A Works Consulted page starts on a separate page and follows the Works Cited page. It follows the same formatting guidelines as a Works Cited page, but you will use Works Consulted (or Additional Resources) as the title.

If you’re unsure of what to include in your citations list (works cited, works consulted, or both), ask your instructor. For the rest of this article, we will refer to this page as the MLA bibliography.

MLA bibliography formatting guidelines

These are the formatting rules you need to follow to create your bibliography according to MLA’s current edition guidelines. Your first page(s) will be your Works Cited page(s) and include the references that you directly refer to in your paper. Usually, this is all that is needed. If your instructor wants you to also include the works you consulted but did not include in your paper (more like a bibliography), then add Works Consulted or Additional Resources page for these sources.

• Your MLA Works Cited (and Works Consulted or Additional Resources pages) should begin on a separate page or pages at the end of your essay.
• Your essay should have a header on every page that includes your last name and the page number.
• The last name/page number header should be on the top right of each page with a ½ inch margin from the top of the page.
• One-inch margins.
• Title the page Works Cited (no italicization or quotation marks) unless otherwise instructed. Center the title. The top should look like this:

• Only center the Works Cited title; all citations should be left-justified.
• Double-space citations.
• Do not add an additional space between citations.
• After the first line, use a hanging indent of ½ inch on all additional lines of a citation. The hanging indent should look like this:

• Typically, this is the author’s last name, but sometimes it could be the title of the source if the author’s name is not available.

If you have a Works Consulted or Additional Resources page after your Works Cited page, format it in the same way, but with the title of Works Consulted or Additional Resources instead of Works Cited. Alternatively, your instructor may require a bibliography. If this is the case, all your sources, whether they are cited in your paper are not, are listed on the same page.

MLA citation guidelines

These are the rules you need to follow to create citations for an MLA bibliography. This section contains information on how to correctly use author names, punctuation, capitalization, fonts, page numbers, DOIs, and URLS in the citations on your MLA bibliography.

Author names

After the title Works Cited, the last name of the author of a source should be the first thing to appear on your page.

List the author’s last name followed by a comma, then the first name followed by the middle name or middle initial if applicable, without a comma separating the first and middle names. Add a period after the name.

Rowling, J.K.

Smith, Alexander McCall.

• Do not include titles such as Dr., Mrs., etc. or professional qualifications such as PhD, M.S., etc. with author names.
• Include suffixes such as Jr. or III after the author’s first name. Separate the first name and the suffix by a comma unless the suffix is a numeral. For example, to cite an author named John Smith, Jr., you would type Smith, John, Jr.

Sources with two authors

For a source with two authors, list the author names in your citation in the order they appear on the source, not alphabetically.

Type the last name of the first author listed on the source followed by a comma, then the first author’s first name followed by a comma. Then type the word “and” then list the second author’s first name and last name in the standard order. Follow the second name with a period.

Include middle names or initials and suffixes when applicable according to the guidelines for one author as listed above.

1st Author’s Last Name, First Name, and 2nd Author’s First Name Last Name.

Lutz, Lisa, and David Hayward.

Clark, Mary Higgins, and Alafair Burke.

Sources with three or more authors

For a source with three or more authors, only type the last and first name of the first author listed in the source, followed by a comma and the phrase et al., which is Latin for “and others.” Be sure to always place a period after the al in et al. but never after the et.

1st Author’s Last Name, First Name, et al.

Charaipotra, Sona, et al.

Williams, Beatriz, et al. All the Ways We Said Goodbye . HarperLuxe, 2020.

Organizations and corporations as authors

For sources with organizations or corporations listed as the author, type the name of the corporation in place of an author’s name. If the organization begins with an article like a, an, or the, it should be excluded in the Works Cited entry.

Modern Language Association of America. MLA Handbook . 2016.

*Note: If the organization is listed as both the author and the publisher, begin the citation with the title and include the organization’s name within the publisher field instead. 

For a source with no author listed, simply omit the author’s name and begin the citation with the title of the source. Use the first letter of the title when considering alphabetical order in your MLA bibliography.

Capitalization

Use MLA title case when citing titles of sources.

• Nouns, pronouns, verbs, adverbs, adjectives, and subordinating conjunctions should be capitalized.
• Articles, prepositions, and coordinating conjunctions should not be capitalized.

Font formatting

• Italicize the titles of larger works such as magazines and books. Also, italicize database and website names.
• Instead of italicization, use quotation marks around titles of shorter works such as poems, short stories, and articles.
• End all bibliography citations with a period.

Page numbers

Include page numbers in your full citations whenever possible. This helps the reader find the information you cited more quickly than if you just cited the entire source and lends more credibility to your argument. If you cite different pages from the same source within your paper, you should cite the entire source on your MLA bibliography instead of listing all of the page numbers you used.

When including page numbers in a citation, use the abbreviation p. to cite one page and the abbreviation pp. to cite multiple pages with a hyphen between the page numbers.

p. 25 or pp. 16-37

When citing page numbers in MLA, omit the first set of repeated digits.

pp. 365-69, not pp. 365-369

DOIs and URLs

A Digital Object Identifier (DOI) is used to locate and identify an online source. While URLs may change or web pages might be edited or updated, a DOI is permanent and therefore more useful in a source citation.

• Use a DOI (digital object identifier) whenever possible. Otherwise use a permalink or URL.
• DOIs should be formatted with “https://doi.org/” before the DOI number.
• Do not include “http://” or “https://” in your URLs.
• As either one will be the last part of your citation, place a period after the DOI or URL. (Note that this period is not part of the DOI or URL.)

Accessed dates

Since the previous 8th edition of the MLA Handbook was published, you do NOT need to list an accessed date for a stable source (e.g., online newspaper article, journal article, photograph, etc.). However, including an access date is good to include when a source does not have a publishing date, and some instructors will request that accessed dates be included for all sources.

If you do include an access date, here’s how to format it:

• Place it at the end of the citation without “http://” or “https://”.
• Write “Accessed” first, followed by the date accessed.
• The date accessed should be formatted as Day Month (abbreviated) Year.

Note: If you choose to list an accessed date after a DOI, the accessed date part of the citation will follow the period after the DOI and will end with a period at the end of the citation

MLA 8 th edition vs MLA 9 th edition

The 9 th edition of the MLA handbook re-introduces guidelines regarding paper formatting (which were not present in the 8 th edition). The guidance in the 9 th addition is consistent with the guidance in previous editions and expands on the formatting of tables, figures/illustrations, and lists. The 9 th edition also offers new guidance in areas like annotated bibliographies, inclusive language, and footnotes/endnotes.

Many of the differences between the 8 th edition and 9 th edition have to do with the formatting of the core elements in reference list entries. Some of the main changes include:

An MLA bibliography is similar to the Works Cited list that you include at the end of your paper. The only difference between a Works Cited list and a bibliography is that for the former, you need to include the entries for only the sources you cited in the text, whereas for the latter you can also include the sources you consulted to write your paper but didn’t directly cite in your writing. MLA generally prefers Works Cited lists to bibliographies.

If your instructor advises you to create an MLA bibliography, follow the same guidelines you would follow for creating an MLA Works Cited list.

The bibliography list appears at the end of the paper, after any endnotes if they are present.

All margins (top, bottom, left, and right) should be set at 1 inch.

Write the running head in the top right of the page at 0.5 inch from the top. Use the running head “Surname Page #.”

The font should be clear enough to read. Use Times New Roman font of size 12 points.

Entries should be double-spaced. If any entry runs over more than a line, indent the subsequent lines of the entry 0.5 inch from the left margin.

Bibliographic entries are arranged alphabetically according to the first item in each entry.

Title your bibliography as “Bibliography.”

Riccio, Thomas. “Reimagining Yup’ik and Inupiat Performance.” Northwest Theatre Review , vol. 12, no. 1, 1999, pp. 1–30.

General rules for creating an annotated bibliography

The annotation is given after the source entry and is generally about 100-150 words in length. The annotation should be indented 1 inch from the left margin to distinguish it from the hanging indent within the citation entry.

The annotation, in general, should be written as short phrases. However, you may use full sentences as well.

The annotation for each source is usually no longer than one paragraph. However, if multiple paragraphs are included, indent the second and subsequent paragraphs without any extra line space between them.

The annotation provides basic information about the source, but does not include details about the source, quotes from the author, etc. The information can be descriptive (by generally describing what the source covers) or evaluative (by evaluating the source’s usefulness to the argument in your paper).

Example annotated bibliography

The below is an example of an annotated bibliography:

Morritt, Robert D. Beringia: Archaic Migrations into North America . Cambridge Scholars Pub, 2011.

The author studies the migration of cultures from Asia to North America. The connection between the North American Athabaskan language family and Siberia is presented, together with comparisons and examinations of the implications of linguistics from anthropological, archaeological, and folklore perspectives. This book explores the origins of the earliest people in the Americas, including Siberian, Dene, and Navajo Creation myths; linguistic comparisons between Siberian Ket Navajo and Western Apache; and comparisons between indigenous groups that appear to share the same origin.

An extended essay must reflect intellectual honesty in research practices and provide the reader with the exact  sources of quotations, ideas and points of view through accurate bibliographies and referencing. Producing accurate citations, referencing and a bibliography is a skill that students should be seeking to perfect. Documenting the research in this way is vital: it allows readers to evaluate the evidence for themselves and it shows the student’s understanding of the importance of the sources used.

Failure to comply with this requirement will be viewed as plagiarism and will, therefore, be treated as a case of malpractice.

What is a bibliography?

A bibliography is an alphabetical list of every source used to research and write the essay. Sources that are not cited in the body of the essay, but were  important in informing the approach taken, should be cited in the introduction or in an acknowledgment. The bibliography should list only those sources cited.

There are a number of different documentation styles available for use when writing research papers; most are appropriate in some academic disciplines but not others. The supervisor should help the student decide on a style for the particular subject of the essay. It is important to remember that, whatever style is chosen, it must be applied consistently. When choosing the documentation style, the student needs to have a clear understanding of how it is to be used before embarking on the research task. The documentation style should be applied in both th e fi nal draft of the essay and in the initial research stages of taking notes. This is good practice, not only for producing a high-quality final product, but also for reducing the opportunities and temptation to plagiarize.

What is a reference?

A reference is a way of indicating to the reader, in an orderly form, where information has been obtained. A reference provides all the information needed to find the source material.  References must be cited because they acknowledge the sources used, and enable the reader to consult the work and verify the data that has been presented.

References must be given whenever someone else’s work is quoted or summarized. References can come from many different sources, including books, magazines, journals, newspapers, emails, internet sites and interviews.

Internet references should include the title of the extract used as well as the website address, the date it was accessed and, if possible, the author. Caution should be exercised with information on websites that do not give references or that cannot be cross-checked against other sources. The more important a particular point is to the essay, the more the quality of its source needs to be evaluated.

Any references to interviews should state the name of the interviewer, the name of the interviewee, the date and the place of the interview.

What is a citation?

A citation is a shorthand method of making a reference in the body of an essay, which is then linked to the full reference at the end of the essay. A citation provides the reader with accurate references so that he or she can locate the source easily. How sources are cited varies with the particular documentation style that has been chosen.

Page numbers should normally be given when referencing printed material: in some styles this will be in the citation, in others in the full reference. Once again, it is important to emphasize that there must be consistency of method when citing sources.

Appendices, footnotes and endnotes

Appendices, footnotes and endnotes are not an essential section of the extended essay and examiners are not required to read them, so care should be taken to include all information of direct relevance to the analysis and argument in the main body of the essay. An essay that attempts to evade the word limit by including important material in notes or appendices risks losing marks under several criteria.

Unless considered essential, complete lists of raw data should not be included in the extended essay.

Students should not constantly refer to material presented in an appendix as this may disrupt the continuity of the essay.

(Handbook, p. 10-12.)

MLA Style is the required style used at ASM for research papers in the Humanities.

MLA style was created by the Modern Language Association of America. It is a set of rules for publications, including research papers.

There are two parts to MLA: In-text citations and the Works Cited list.

In MLA, you must "cite" sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:

• In the body of your paper where you add a brief in-text citation.
• In the Works Cited list at the end of your paper where you give more complete information for the source.

Core Elements of an MLA Citation

MLA 8th edition provides 9 core elements to complete any works cited entry. It is your job to try to fill in these core elements with the information you have about a source. If any element is missing or not applicable, you can skip that element.

Author. "Title of source." (title is in italics if the source is self-contained. For example, an entire book.)

Title of Container,  (for example, the title of a book, journal, web site) Other contributors, (such as editors, translators, or directors.) Version,  Number,  Publisher, Publication date, Location.

Note:  According to p. 42 of the  MLA Handbook , publisher information may be omitted for:

• periodicals (journals, magazines, newspapers)
• works published by an author or editor
• web sites whose title is the same as the name of the publisher
• a web site not involved in producing the work it makes (e.g. user-generated content sites like  YouTube )

APA style  (also known as APA format) is a writing style and format for academic documents such as  scholarly journal  articles and books. It is commonly used for citing sources within the field of behavioral and social sciences, including sociology, education, nursing, criminal justice, and anthropology, as well as psychology. It is described in the style guide of the American Psychological Association (APA), which is titled the  Publication Manual of the American Psychological Association.

Harvard Guide to Using Sources 

• The Honor Code
• Bibliography

If you are using Chicago style footnotes or endnotes, you should include a bibliography at the end of your paper that provides complete citation information for all of the sources you cite in your paper. Bibliography entries are formatted differently from notes. For bibliography entries, you list the sources alphabetically by last name, so you will list the last name of the author or creator first in each entry. You should single-space within a bibliography entry and double-space between them. When an entry goes longer than one line, use a hanging indent of .5 inches for subsequent lines. Here’s a link to a sample bibliography that shows layout and spacing . You can find a sample of note format here .

Complete note vs. shortened note

Here’s an example of a complete note and a shortened version of a note for a book:

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35.

1. Karen Ho, Liquidated , 27-35.

Note vs. Bibliography entry

The bibliography entry that corresponds with each note is very similar to the longer version of the note, except that the author’s last and first name are reversed in the bibliography entry. To see differences between note and bibliography entries for different types of sources, check this section of the Chicago Manual of Style .

For Liquidated , the bibliography entry would look like this:

Ho, Karen, Liquidated: An Ethnography of Wall Street . Durham: Duke University Press, 2009.

Citing a source with two or three authors

If you are citing a source with two or three authors, list their names in your note in the order they appear in the original source. In the bibliography, invert only the name of the first author and use “and” before the last named author.

1. Melissa Borja and Jacob Gibson, “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees,” The Review of Faith & International Affairs 17, no. 3 (2019): 80-81, https://doi.org/10.1080/15570274.2019.1643983 .

Shortened note:

1. Borja and Gibson, “Internationalism with Evangelical Characteristics,” 80-81.

Bibliography:

Borja, Melissa, and Jacob Gibson. “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees.” The Review of Faith & International Affairs 17. no. 3 (2019): 80–93. https://doi.org/10.1080/15570274.2019.1643983 .

Citing a source with more than three authors

If you are citing a source with more than three authors, include all of them in the bibliography, but only include the first one in the note, followed by et al. ( et al. is the shortened form of the Latin et alia , which means “and others”).

1. Justine M. Nagurney, et al., “Risk Factors for Disability After Emergency Department Discharge in Older Adults,” Academic Emergency Medicine 27, no. 12 (2020): 1271.

Short version of note:

1. Justine M. Nagurney, et al., “Risk Factors for Disability,” 1271.

Nagurney, Justine M., Ling Han, Linda Leo‐Summers, Heather G. Allore, Thomas M. Gill, and Ula Hwang. “Risk Factors for Disability After Emergency Department Discharge in Older Adults.” Academic Emergency Medicine 27, no. 12 (2020): 1270–78. https://doi.org/10.1111/acem.14088 .

Citing a book consulted online

If you are citing a book you consulted online, you should include a URL, DOI, or the name of the database where you found the book.

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35, https://doi-org.ezp-prod1.hul.harvard.edu/10.1215/9780822391371 .

Citing an e-book consulted outside of a database

If you are citing an e-book that you accessed outside of a database, you should indicate the format. If you read the book in a format without fixed page numbers (like Kindle, for example), you should not include the page numbers that you saw as you read. Instead, include chapter or section numbers, if possible.

How to Cite Sources | Citation Generator & Quick Guide

Citing your sources is essential in  academic writing . Whenever you quote or paraphrase a source (such as a book, article, or webpage), you have to include a  citation crediting the original author.

Failing to properly cite your sources counts as plagiarism , since you’re presenting someone else’s ideas as if they were your own.

The most commonly used citation styles are APA and MLA. The free Scribbr Citation Generator is the quickest way to cite sources in these styles. Simply enter the URL, DOI, or title, and we’ll generate an accurate, correctly formatted citation.

Citation examples and full guides, frequently asked questions about citing sources.

Citations are required in all types of academic texts. They are needed for several reasons:

• To avoid plagiarism by indicating when you’re taking information from another source
• To give proper credit to the author of that source
• To allow the reader to consult your sources for themselves

A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:

• To quote a source , copy a short piece of text word for word and put it inside quotation marks .
• To paraphrase a source , put the text into your own words. It’s important that the paraphrase is not too close to the original wording. You can use the paraphrasing tool if you don’t want to do this manually.

Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.

In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:

• APA Style is widely used in the social sciences and beyond.
• MLA style is common in the humanities.
• Chicago notes and bibliography , common in the humanities
• Chicago author-date , used in the (social) sciences
• There are many other citation styles for different disciplines.

If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.

In most styles, your citations consist of:

• Brief in-text citations at the relevant points in the text
• A reference list or bibliography containing full information on all the sources you’ve cited

In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).

An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.

There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.

A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.

The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:

• Author name
• Publication date
• Container (e.g., the book an essay was published in, the journal an article appeared in)
• Location (e.g., a URL or DOI , or sometimes a physical location)

The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.

Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.

In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.

Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.

Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.

Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .

Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

You can find all the citation styles and locales used in the Scribbr Citation Generator in our publicly accessible repository on Github .

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

MLA Style  is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

Literature Review

• What is a Literature Review?
• What is NOT a Literature Review?
• Purposes of a Literature Review
• Types of Literature Reviews
• Literature Reviews vs. Systematic Reviews
• Systematic vs. Meta-Analysis

Literature Review  is a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.

Also, we can define a literature review as the collected body of scholarly works related to a topic:

• Summarizes and analyzes previous research relevant to a topic
• Includes scholarly books and articles published in academic journals
• Can be an specific scholarly paper or a section in a research paper

The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic

• Help gather ideas or information
• Keep up to date in current trends and findings
• Help develop new questions

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Helps focus your own research questions or problems
• Discovers relationships between research studies/ideas.
• Suggests unexplored ideas or populations
• Identifies major themes, concepts, and researchers on a topic.
• Tests assumptions; may help counter preconceived ideas and remove unconscious bias.
• Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches.
• Indicates potential directions for future research.

All content in this section is from Literature Review Research from Old Dominion University 

Keep in mind the following, a literature review is NOT:

Not an essay 

Not an annotated bibliography  in which you summarize each article that you have reviewed.  A literature review goes beyond basic summarizing to focus on the critical analysis of the reviewed works and their relationship to your research question.

Not a research paper   where you select resources to support one side of an issue versus another.  A lit review should explain and consider all sides of an argument in order to avoid bias, and areas of agreement and disagreement should be highlighted.

A literature review serves several purposes. For example, it

• provides thorough knowledge of previous studies; introduces seminal works.
• helps focus one’s own research topic.
• identifies a conceptual framework for one’s own research questions or problems; indicates potential directions for future research.
• suggests previously unused or underused methodologies, designs, quantitative and qualitative strategies.
• identifies gaps in previous studies; identifies flawed methodologies and/or theoretical approaches; avoids replication of mistakes.
• helps the researcher avoid repetition of earlier research.
• suggests unexplored populations.
• determines whether past studies agree or disagree; identifies controversy in the literature.
• tests assumptions; may help counter preconceived ideas and remove unconscious bias.

As Kennedy (2007) notes*, it is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the original studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field. In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.

Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are several approaches to how they can be done, depending upon the type of analysis underpinning your study. Listed below are definitions of types of literature reviews:

Argumentative Review      This form examines literature selectively in order to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to to make summary claims of the sort found in systematic reviews.

Integrative Review      Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.

Historical Review      Few things rest in isolation from historical precedent. Historical reviews are focused on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review      A review does not always focus on what someone said [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels (i.e. those of theory, substantive fields, research approaches and data collection and analysis techniques), enables researchers to draw on a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection and data analysis, and helps highlight many ethical issues which we should be aware of and consider as we go through our study.

Systematic Review      This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyse data from the studies that are included in the review. Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?"

Theoretical Review      The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review help establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

What's in the name? The difference between a Systematic Review and a Literature Review, and why it matters . By Lynn Kysh from University of Southern California

Systematic review or meta-analysis?

A  systematic review  answers a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria.

A  meta-analysis  is the use of statistical methods to summarize the results of these studies.

Systematic reviews, just like other research articles, can be of varying quality. They are a significant piece of work (the Centre for Reviews and Dissemination at York estimates that a team will take 9-24 months), and to be useful to other researchers and practitioners they should have:

• clearly stated objectives with pre-defined eligibility criteria for studies
• explicit, reproducible methodology
• a systematic search that attempts to identify all studies
• assessment of the validity of the findings of the included studies (e.g. risk of bias)
• systematic presentation, and synthesis, of the characteristics and findings of the included studies

Not all systematic reviews contain meta-analysis. 

Meta-analysis is the use of statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects of health care than those derived from the individual studies included within a review.  More information on meta-analyses can be found in  Cochrane Handbook, Chapter 9 .

A meta-analysis goes beyond critique and integration and conducts secondary statistical analysis on the outcomes of similar studies.  It is a systematic review that uses quantitative methods to synthesize and summarize the results.

An advantage of a meta-analysis is the ability to be completely objective in evaluating research findings.  Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted.  In that case, an integrative review is an appropriate strategy.

What Is an Annotated Bibliography - and Why Write it at the Beginning of Your Research?

An annotated bibliography is a bibliography that includes a summary and/or evaluation of each of the sources. Each citation is followed by a brief note – or annotation – that describes various aspects of the source such as a summary, an evaluation of the content, and applicability to your topic.

Why should an annotated bibliography come at the BEGINNING of your research assignment?   A researcher can use an annotated bibliography to do a critical summary of each source: its importance, its strengths and weaknesses, and the ways in which the source will fit into your research. When doing an annotated bibliography, researchers analyze and don't summarize.

How Can a Good Annotated Bibliography Help Me With My EE?

The process is not just a matter of listing possible sources. It also requires you to think critically. Consider your sources in terms of:

• what has already been written about their chosen topic and
• how your own research will fit into this.

As you examine each source, you will need to identify the issues and different perspectives of others. This will help you to develop a reasoned argument.

• allow you to keep track of your reading
• encourage you to think critically about the sources you are using in relation to your research area
• allow you, quite early on in the process, to become aware of possible concerns about using certain sources
• help you determine whether a source is of use to you in your research
• help you to justify your use of particular sources, both to your supervisor and to the IB examiner who will be reading your essay
• help you with the planning of your research, and ultimately save you time
• enable you to develop critical-thinking skills in selecting and evaluating source material.

• the bibliographic information
• the annotations (a concise summary of the source).

The annotations will vary in length depending on whether you are writing a summary of the source or analyzing it.

A summary should include:         

• a concise summary of the content and theme(s) of the source
• a comment on the authority of the author
• a comment on the purpose of the source
• a comment on how this source might be useful.

What Should the Annotation Include?

This video tutorial from Champlain College Library explains what an annotated bibliography is and what each annotation should include.  The short paragraphs describing each source on the list should summarize the source, evaluate it, and discuss how it would fit into your topic.

How Do I Write an Annotation?

The Cornell University Library has defined an annotated bibliography as: a list of citations to books, articles, and documents. Each citation is followed by a brief  (usually about 150 words)  descriptive and evaluative paragraph. This means you are creating a paragraph that others may read to get a general idea of what your sources are about. The hardest part is being concise with your information. Annotations take practice but once you get the hang of it they are easy. Here are the steps to follow:   Step 1: Talk about the author. (1 sentence) Is this a professor? Maybe this is a professional in the field? Or is this person a hobbyist? Tell the audience about the author in the first part of the annotation. Step 2: Explain what the article is about. (1-3 sentences) Tell the audience what is in the article. This is the most difficult part of the annotation because it requires you to be very succinct. Don’t rewrite the article; just write the base facts and important notes about the article here. Step 3: Explain how this article illuminates your bibliography topic. (1-2 sentences) What about this article makes it relevant to your topic? Why did you select it? What pertinent bit of information makes this article stand out among the others? Step 4: Compare or contrast this work with another you have cited. (1-2 sentences) How does this specific article relate to another article in your annotated bibliography? Do they agree or not? Why not? What makes them unique?

Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

• encourages you to think critically about the content of the works you are using, their place within a field of study, and their relation to your own research and ideas.
• proves you have read and understand your sources.
• establishes your work as a valid source and you as a competent researcher.
• situates your study and topic in a continuing professional conversation.
• provides a way for others to decide whether a source will be helpful to their research if they read it.
• could help interested researchers determine whether they are interested in a topic by providing background information and an idea of the kind of work going on in a field.

What elements might an annotation include?

• Bibliography according to the appropriate citation style (MLA, APA, CBE/CSE, etc.).
• Explanation of main points and/or purpose of the work—basically, its thesis—which shows among other things that you have read and thoroughly understand the source.
• Verification or critique of the authority or qualifications of the author.
• Comments on the worth, effectiveness, and usefulness of the work in terms of both the topic being researched and/or your own research project.
• The point of view or perspective from which the work was written. For instance, you may note whether the author seemed to have particular biases or was trying to reach a particular audience.
• Relevant links to other work done in the area, like related sources, possibly including a comparison with some of those already on your list. You may want to establish connections to other aspects of the same argument or opposing views.

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about their preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since they may have a different style they want you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

• MLA documentation is generally used for disciplines in the humanities, such as English, languages, film, and cultural studies or other theoretical studies. These annotations are often summary or analytical annotations.
• Title your annotated bibliography “Annotated Bibliography” or “Annotated List of Works Cited.”
• Following MLA format, use a hanging indent for your bibliographic information. This means the first line is not indented and all the other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• Begin your annotation immediately after the bibliographic information of the source ends; don’t skip a line down unless you have been told to do so by your instructor.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

• Natural and social sciences, such as psychology, nursing, sociology, and social work, use APA documentation. It is also used in economics, business, and criminology. These annotations are often succinct summaries.
• Annotated bibliographies for APA format do not require a special title. Use the usual “References” designation.
• Like MLA, APA uses a hanging indent: the first line is set flush with the left margin, and all other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line.
• The entire annotation is indented an additional two spaces, so that means each of its lines will be six spaces from the margin (if your instructor has said that it’s okay to tab over instead of using the four spaces rule, indent the annotation two more spaces in from that point).

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

• CBE/CSE documentation is used by the plant sciences, zoology, microbiology, and many of the medical sciences.
• Annotated bibliographies for CBE/CSE format do not require a special title. Use the usual “References,” “Cited References,” or “Literature Cited,” and set it flush with the left margin.
• Bibliographies for CSE in general are in a slightly smaller font than the rest of the paper.
• When using the name-year system, as in MLA and APA, the first line of each entry is set flush with the left margin, and all subsequent lines, including the annotation, are indented three or four spaces.
• When using the citation-sequence method, each entry begins two spaces after the number, and every line, including the annotation, will be indented to match the beginning of the entry, or may be slightly further indented, as in the case of journals.
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line. The entire annotation follows the indentation of the bibliographic entry, whether it’s N-Y or C-S format.
• Annotations in CBE/CSE are generally a smaller font size than the rest of the bibliographic information.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what they want or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

• They sum up the content of the source, as a book report might.
• They give an overview of the arguments and proofs/evidence addressed in the work and note the resulting conclusion.
• They do not judge the work they are discussing. Leave that to the critical/evaluative annotations.
• When appropriate, they describe the author’s methodology or approach to material. For instance, you might mention if the source is an ethnography or if the author employs a particular kind of theory.

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

• evaluate the source or author critically (biases, lack of evidence, objective, etc.).
• show how the work may or may not be useful for a particular field of study or audience.
• explain how researching this material assisted your own project.

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that they expect a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!
