Creating a Chicago Style Bibliography | Format & Examples

Published on September 23, 2019 by Jack Caulfield . Revised on December 5, 2022.

A Chicago style bibliography lists the sources cited in your text. Each bibliography entry begins with the author’s name and the title of the source, followed by relevant publication details. The bibliography is alphabetized by authors’ last names.

A bibliography is not mandatory, but is strongly recommended for all but very short papers. It gives your reader an overview of all your sources in one place. Check with your instructor if you’re not sure whether you need a bibliography.

Always make sure to pay attention to punctuation (e.g., commas , quotation marks , parentheses ) in your citations.

Bibliography entries vary in format depending on the type of source . Templates and examples for the most common source types are shown below.

• Book chapter
• Journal article
• The edition is always abbreviated (e.g. 2nd ed. or rev. ed.).
• Only include the URL for books you consulted online.
• Use this format to cite a chapter in a multi-authored book. If all the chapters in a book were written by the same person, reference the whole book.
• Begin the citation with the author of the chapter. The editor who compiled the book is listed later.
• The page range identifies the location of the article within the journal issue.
• For articles accessed online, include a DOI (digital object identifier) where available, and a URL if not.
• If the author is unknown, list the organization or website name as author, and don’t repeat it later in the citation.
• If no publication date is listed, include an access date instead.
• The website name is not italicized, unless it is an online version of a newspaper or magazine .

The bibliography appears at the end of your text. The heading Bibliography is bolded and centred at the top of the page.

Unlike the rest of a Chicago format paper, the bibliography is not double-spaced. However, add a single line space between entries.

If a bibliography entry extends onto more than one line, subsequent lines should be indented ( hanging indent ), as seen in the example below. This helps the reader to see at a glance where each new entry begins.

There are further guidelines for formatting a Chicago style annotated bibliography , in which you write a paragraph of summary and source evaluation under each source.

Author names in the bibliography are inverted: The last name comes first, then the first name(s). Sources are alphabetized by author last name.

If a source has no named author, alphabetize by the first word of the title or organization name that starts the entry. Ignore articles (“the,” “a,” and “an”) for the purposes of alphabetization.

Sources with multiple authors

For sources with more than one author, only the first author’s name is inverted; subsequent names are written in the normal order.

For texts with up to 10 authors, all the authors’ names should be listed in the order they appear in the source, separated by commas .

If there are more than 10 authors, list the first seven, followed by “ et al. ”

Multiple sources by the same author

If you include multiple works from the same author, only include the author name in the first entry. In subsequent entries, replace the name with three em dashes , followed by the rest of the citation formatted as normal. List the entries in alphabetical order by title.

A reference list is mandatory in Chicago author-date style , where you cite sources in parentheses in the text. The only differences between a Chicago bibliography and a reference list are the heading and the placement of the date.

The reference list is headed “References.” In reference list entries, the publication date is placed immediately after the author’s name. This allows the reader to easily find a reference on the basis of the corresponding in-text citation.

Prevent plagiarism. Run a free check.

In a Chicago style footnote , list up to three authors. If there are more than three, name only the first author, followed by “ et al. “

In the bibliography , list up to 10 authors. If there are more than 10, list the first seven followed by “et al.”

The same rules apply in Chicago author-date style .

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

In a Chicago footnote citation , when the author of a source is unknown (as is often the case with websites ), start the citation with the title in a full note. In short notes and bibliography entries, list the organization that published it as the author.

In Chicago author-date style , treat the organization as author in your in-text citations and reference list.

When an online source does not list a publication date, replace it with an access date in your Chicago footnotes and your bibliography :

If you are using author-date in-text citations , or if the source was not accessed online, replace the date with “n.d.”

• A reference list is used with Chicago author-date citations .
• A bibliography is used with Chicago footnote citations .

Both present the exact same information; the only difference is the placement of the year in source citations:

• In a reference list entry, the publication year appears directly after the author’s name.
• In a bibliography entry, the year appears near the end of the entry (the exact placement depends on the source type).

There are also other types of bibliography that work as stand-alone texts, such as a Chicago annotated bibliography .

In Chicago author-date style , your text must include a reference list . It appears at the end of your paper and gives full details of every source you cited.

In notes and bibliography style, you use Chicago style footnotes to cite sources; a bibliography is optional but recommended. If you don’t include one, be sure to use a full note for the first citation of each source.

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.

Harvard Style Bibliography | Format & Examples

Published on 1 May 2020 by Jack Caulfield . Revised on 7 November 2022.

In Harvard style , the bibliography or reference list provides full references for the sources you used in your writing.

• A reference list consists of entries corresponding to your in-text citations .
• A bibliography sometimes also lists sources that you consulted for background research, but did not cite in your text.

The two terms are sometimes used interchangeably. If in doubt about which to include, check with your instructor or department.

The information you include in a reference varies depending on the type of source, but it usually includes the author, date, and title of the work, followed by details of where it was published. You can automatically generate accurate references using our free reference generator:

Sources are alphabetised by author last name. The heading ‘Reference list’ or ‘Bibliography’ appears at the top.

Each new source appears on a new line, and when an entry for a single source extends onto a second line, a hanging indent is used:

Prevent plagiarism, run a free check.

Reference list or bibliography entries always start with the author’s last name and initial, the publication date and the title of the source. The other information required varies depending on the source type. Formats and examples for the most common source types are given below.

• Book chapter
• Translated book

When a source has up to three authors, list all of them in the order their names appear on the source. If there are four or more, give only the first name followed by ‘ et al. ’:

Sometimes a source won’t list all the information you need for your reference. Here’s what to do when you don’t know the publication date or author of a source.

Some online sources, as well as historical documents, may lack a clear publication date. In these cases, you can replace the date in the reference list entry with the words ‘no date’. With online sources, you still include an access date at the end:

When a source doesn’t list an author, you can often list a corporate source as an author instead, as with ‘Scribbr’ in the above example. When that’s not possible, begin the entry with the title instead of the author:

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

To create a hanging indent for your bibliography or reference list :

• Highlight all the entries
• Click on the arrow in the bottom-right corner of the ‘Paragraph’ tab in the top menu.
• In the pop-up window, under ‘Special’ in the ‘Indentation’ section, use the drop-down menu to select ‘Hanging’.
• Then close the window with ‘OK’.

How to Write a Bibliography (MLA, APA Examples)

Learn how to easily write a bibliography by following the format outlined in this article.

This resource will help your students properly cite different resources in the bibliography of a research paper, and how to format those citations, for books, encyclopedias, films, websites, and people.

What is a bibliography?

According to Infoplease.com, A bibliography is a list of the types of sources you used to get information for your report. It is included at the end of your report, on the last page (or last few pages).

What are the types of bibliography styles (MLA, APA, etc.)?

The 3 most common bibliography/citation styles are:

• MLA Style: The Modern Language Association works cited page style
• APA Style: The American Psychological Association style
• Chicago Style: The bibliography style defined by the Chicago Manual of Style

We’ll give examples of how to create bibliography entries in various styles further down in this article. 

What sources do you put in a bibliography?

An annotated bibliography should include a reference list of any sources you use in writing a research paper. Any printed sources from which you use a text citation, including books, websites, newspaper articles, journal articles, academic writing, online sources (such as PDFs), and magazines should be included in a reference list. In some cases, you may need or want to cite conversations or interviews, works of art, visual works such as movies, television shows, or documentaries - these (and many others) can also be included in a reference list.

How to get started writing your bibliography

You will find it easier to prepare your MLA, APA, or Chicago annotated bibliography if you keep track of each book, encyclopedia, journal article, webpage or online source you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author’s last name, place of publication, web address, publisher, and date of publication for each source.

How to Write a Bibliography for a Research Paper

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

Academic Writing, Editing, Proofreading, And Problem Solving Services

Get 10% off with 24start discount code, assembling bibliographies and works cited.

• If your assignment calls for a bibliography, list all the sources you consulted in your research.
• If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
• If your works cited page includes a source that you did not cite in your paper, delete it.
• All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

• A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
• A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

• Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
• Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
• Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
• Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!

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.”

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.

• 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 .

Bibliography entry:

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