Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Since The Chicago Manual of Style (CMOS) is primarily intended as a style guide for published works rather than class papers, these guidelines will be supplemented with information from, Kate L. Turabian’s Manual for Writers of Research Papers, Theses, and Dissertations (8th ed.), which is largely based on CMOS with some slight alterations.

To see a side-by-side comparison of the three most widely used citation styles, including a chart of all CMOS citation guidelines, see the Citation Style Chart.

Please use the example at the bottom of this page to cite the Purdue OWL in CMOS.

A Note on Citations

Unlike many citation styles, CMOS gives writers two different methods for documenting sources: the Author-Date System and the Notes-Bibliography (NB) System.  As its name suggests, Author-Date uses parenthetical citations in the text to reference the source's author's last name and the year of publication. Each parenthetical citation corresponds to an entry on a References page that concludes the document. In these regards, Author-Date is very similar to, for instance, APA style.

By contrast, NB uses numbered footnotes in the text to direct the reader to a shortened citation at the bottom of the page. This corresponds to a fuller citation on a Bibliography page that concludes the document. Though the general principles of citation are the same here, the citations themselves are formatted differently from the way they appear in Author-Date.

If you are using CMOS for school or work, don't forget to ensure that you're using your organization's preferred citation method. For examples of these two different styles in action, see our CMOS sample papers:

Author-Date Sample Paper

NB Sample Paper

General CMOS Guidelines

• Text should be consistently double-spaced, except for block quotations, notes, bibliography entries, table titles, and figure captions.
• A prose quotation of five or more lines, or more than 100 words, should be blocked.
• CMOS recommends blocking two or more lines of poetry.
• A blocked quotation does not get enclosed in quotation marks.
• A blocked quotation must always begin a new line.
• Blocked quotations should be indented with the word processor’s indention tool.
• Page numbers begin in the header of the first page of text with Arabic number 1.
• For CMOS and Turabian’s recommendations, see “Headings,” below.

Supplemental Turabian Style Guidelines

• Margins should be set at no less than 1”.
• Typeface should be something readable, such as Times New Roman or Courier.
• Font size should be no less than 10 pt. (preferably, 12 pt.).

Major Paper Sections

• The title should be centered a third of the way down the page.
• Your name, class information, and the date should follow several lines later.
• For subtitles, end the title line with a colon and place the subtitle on the line below the title.
• Double-space each line of the title page.

CMOS Title Page

• Different practices apply for theses and dissertations (see Kate L. Turabian’s A Manual for Writers of Research Papers, Theses, ad Dissertations [8 th ed.].
• Titles mentioned in the text, notes, or bibliography are capitalized “headline-style,” meaning first words of titles and subtitles and any important words thereafter should be capitalized.
• Book and periodical titles (titles of larger works) should be italicized.
• Article and chapter titles (titles of shorter works) should be enclosed in double quotation marks.
• The titles of most poems should be enclosed in double quotation marks, but the titles of very long poems should be italicized.
• Titles of plays should be italicized.
• For example, use lowercase terms to describe periods, except in the case of proper nouns (e.g., “the colonial period,” vs. “the Victorian era”).
• A prose quotation of five or more lines should be “blocked.” The block quotation should match the surrounding text, and it takes no quotation marks. To offset the block quote from surrounding text, indent the entire quotation using the word processor’s indentation tool. It is also possible to offset the block quotation by using a different or smaller font than the surrounding text.
• Label the first page of your back matter, your comprehensive list of sources, “Bibliography” (for Notes and Bibliography style) or “References” (for Author-Date style).
• Leave two blank lines between “Bibliography” or “References” and your first entry.
• Leave one blank line between remaining entries.
• List entries in letter-by-letter alphabetical order according to the first word in each entry, be that the author's name or the title of the piece..
• For two to three authors, write out all names.
• For four to ten authors, write out all names in the bibliography but only the first author’s name plus “et al.” in notes and parenthetical citations.
• When a source has no identifiable author, cite it by its title, both on the references page and in shortened form (up to four keywords from that title) in parenthetical citations throughout the text.
• Write out publishers’ names in full.
• Do not use access dates unless publication dates are unavailable.
• If you cannot ascertain the publication date of a printed work, use the abbreviation “n.d.”
• Provide DOIs instead of URLs whenever possible.
• If no DOI is available, provide a URL.
• If you cannot name a specific page number when called for, you have other options: section (sec.), equation (eq.), volume (vol.), or note (n.).

CMOS Bibliography Page

• Note numbers should begin with “1” and follow consecutively throughout a given paper.
• Note numbers are superscripted.
• Note numbers should be placed at the end of the clause or sentence to which they refer and should be placed after all punctuation, except for the dash.
• Note numbers are full-sized, not raised, and followed by a period (superscripting note numbers in the notes themselves is also acceptable).
• In parenthetical citation, separate documentation from brief commentary with a semicolon.
• Do not repeat the hundreds digit in a page range if it does not change from the beginning to the end of the range.

For more information on footnotes, please see CMOS NB Sample Paper .

While  The Chicago Manual of Style does not include a prescribed system for formatting headings and subheads, it makes several recommendations.

• Maintain consistency and parallel structure in headings and subheads.
• Use headline-style for purposes of capitalization.
• Subheadings should begin on a new line.
• Subheadings can be distinguished by font-size.
• Ensure that each level of hierarchy is clear and consistent.
• Levels of subheads can be differentiated by type style, use of boldface or italics, and placement on the page, usually either centered or flush left.
• Use no more than three levels of hierarchy.
• Avoid ending subheadings with periods.

Turabian has an optional system of five heading levels.

Turabian Subheading Plan

Here is an example of the five-level heading system:

CMOS Headings

Tables and Figures

• Position tables and figures as soon as possible after they are first referenced. If necessary, present them after the paragraph in which they are described.
• For figures, include a caption, or short explanation of the figure or illustration, directly after the figure number.
• Cite a source as you would for parenthetical citation, and include full information in an entry on your Bibliography or References page.
• Acknowledge reproduced or adapted sources appropriately (i.e., photo by; data adapted from; map by...).
• If a table includes data not acquired by the author of the text, include an unnumbered footnote. Introduce the note by the word Source(s) followed by a colon, then include the full source information, and end the note with a period.

How to Cite the Purdue OWL in CMOS

On the new OWL site, contributors’ names and the last edited date are no longer listed at the top of every page. This means that most citations will now begin with the title of the resource, rather than the contributors' names.

Generate citations in Chicago style automatically, with MyBib!

😕 What is a Chicago Citation Generator?

A Chicago Citation Generator is a software tool that automatically generates citations and bibliographies in the Chicago citation style.

Citations can be created by entering an identifying piece of information about a source, such as a website URL, book ISBN, or journal article DOI to the generator. The generator will then create a fully formatted citation in the Chicago style containing all the required information for the source.

Chicago style citations are used to give credit to the authors of supporting work that has been used to write an academic paper or article.

👩‍🎓 Who uses an Chicago Citation Generator?

The Chicago style is primarily used by college and university students studying business, history, social sciences, the fine arts, amongst others.

🙌 Why should I use a Chicago Citation Generator?

Citing sources is often an afterthought in paper writing because formatting citations correctly is time-consuming and confusing, and staying on top of source management manually can be hard. A citation generator makes this easier by:

• Decreasing the time you would spend formatting citations correctly
• Managing the recording and organization of every citation for you

In short, there is no reason not to use a citation generator in academic writing.

⚙️ How do I use MyBib's Chicago Citation Generator?

To get started, scroll up back up to the tool at the top of the page and follow these steps:

• Select the type of source you want to cite
• If it's a website, enter the URL in the search bar. If it's a book, enter the ISBN or title. If it's a journal article, enter the DOI or title. For all other sources, enter the details of the source into the form
• Select the search result that most closely represents the source you referred to in your paper
• Shazam! The generator will automatically format the citation in the Chicago style. Copy it into your paper, or save it to your bibliography to download later
• Repeat for every other citation you need to create for your paper

Arranging Bibliography Entries

ARRANGING BIBLIOGRAPHY ENTRIES

Entries in a bibliography are arranged alphabetically based on the first word(s) of each entry. Usually this means you're alphabetizing by author/editor last name, although entries for anonymous sources do not have author names. Two anonymous sources appear in the "Sample Bibliography" (below at right). See the entries that begin with "Colonial Williamsburg Foundation" and "Osceola (KY) Times."

Multiple entries that begin with the same author/editor last name should be alphabetized based on the remaining word(s) in the author/editor names (see the two entries for Page in the "Sample Bibliography"). For example:

Smith, A. A. Smith, Abby. Smith, Abigail. Smith, John. Smith, John A. Smith, John Abraham. Smith, R. Samuel. Smith, Rex. Smith, Rex, Jr.

When you have multiple entries for works by the same author/editor, the author's full name is replaced with a set of three hyphens beginning with the second entry for that author/editor (see the two entries for Thurber in the "Sample Bibliography"). The multiple entries are alphabetized by the word(s) following the author's/editor's name. For example:

Jones, Jane. Acting Like Myself . ---. "America, My America." ---. Freeing the Inner Me . ---. Methodists and Martians .

Formatting a Bibliography

FORMATTING A BIBLIOGRAPHY

    GUIDANCE:

As with the text of your paper, a bibliography should be double spaced.

Entries in a bibliography are formatted differently than entries in notes. See the other pages of this guide for help with understanding the differences. You can also: 1) consult a copy of the The Chicago Manual of Style ; 2) ask a librarian for help; or 3)  make an appointment with the Writing Center .

Entries in a bibliography should be arranged alphabetically by the initial component of the entry, which is commonly an author's last name.

Entries in a bibliography should use a hanging indent. In other words, for entries that are longer than one line, all lines beyond the first need to be indented, as shown here:

Sample Bibliography

SAMPLE BIBLIOGRAPHY

In an actual paper the entries below would use hanging indents (see explanation above).

Source List

- All citations should be double spaced and have a hanging indent.

- A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

- Label the first page of your your comprehensive list of sources, “Bibliography” (for Notes and Bibliography style) or “References” (for Author-Date style).

- List entries in letter-by-letter alphabetical order according to the first word in each entry, be that the author's name or the title of the piece.

-Leave two blank lines between the title and your first entry. Then, leave one blank line between each entry.

- All citations should use first line indent, where the first line of the footnote should be indented by 0.5 inches; all subsequent lines are not indented.

- Footnotes should be the same font size and style as the rest of your paper.

- Note numbers should begin with “1” and follow consecutively throughout a given paper

See instructions for how to  insert footnotes  in Microsoft Word.

See instructions for how to insert footnotes in Google Docs.

Authors/Editors

- An author can be a person but can also be an organization, or company. These are called group or corporate authors.

- If you are citing a chapter from a book that has an editor, the author of the chapter is listed first, and is the name listed in the in-text citation.

- Capitalize the first letter of every important word in the title. You do not need to capitalize words such as: in, of, or an.

- If there is a colon (:) in the title, include what comes after the colon (also known as the subtitle).

- Page numbers begin in the header of the first page of text with Arabic number 1.

- Margins should be set at no less than 1”.

- The format of all dates is: Month Date, Year. e.g. September 5, 2012.

- Whether to give the year alone or include a month and day depends on your source: write the full date as you find it there.

- If no date is listed, use the abbreviation n.d. for "no date." 

- Typeface should be something readable, such as Times New Roman or Courier.

- Font size should be no less than 10 pt. (preferably, 12 pt.).

- Text should be consistently double-spaced, except for block quotations, notes, bibliography entries, table titles, and figure captions.

In-Text Citations

Notes & Bibliography:

- Note numbers are superscripted.

- Note numbers should be placed at the end of the clause or sentence to which they refer and should be placed after all punctuation, except for the dash.

Introduction

Both footnote/endnote citations and author-date citations require a bibliography or cited reference section.

The way a bibliographic entry is structured will be the same regardless of which in-text citation style you use, with one exception: if you used author-date as your in-text citation style, you will place the publication date immediately after the author section, as opposed to at/near the end. This makes it easier for readers to find the appropriate citation in your reference list.

For example, here is a bibliographic reference entry for the same resource in each style:  

Footnote/Endnote Bibliography

Judt, Tony. A Grand Illusion? An Essay on Europe. New York: Hill and Wang, 1996.

Author-Date Bibliography

Judt, Tony. 1996. A Grand Illusion? An Essay on Europe. New York: Hill and Wang.  

As you can see, the only difference between these two reference entries is the date placement. All other elements are listed in the same order.

  General Bibliography Rules

• The bibliography should start on a new page, 12 pt. font (Times New Roman), and be titled ‘Bibliography’ at the top.
• Leave two blank lines between your bibliography title and the first entry.
• Use proper formatting for each type of source and always using a hanging indent. The first line of the citation will begin on the margin, subsequent lines are indented (opposite of a footnote/endnote).
• The bibliography should be alphabetical.
• Entries should be typed single-space but there should be a blank line between each separate citation.
• If you have multiple bibliographic entries from the same author, it is acceptable to use what is called the ‘3-em’ dash to replace the name of the content creators. For Example:  

Judt, Tony.  A Grand Illusion ?  An Essay on Europe. New York: Hill and Wang, 1996.

—.  Reappraisals: Reflections on the Forgotten Twentieth Century. New York: Penguin Press, 2008.

—, ed.  Resistance and Revolution in Mediterranean Europe, 1939-1948. New York: Routledge, 1989.

Creating a Bibliography in Chicago Style

The bibliography is a list of all the sources used in the paper. The list includes the important publication details of the sources. The bibliography must also follow this format:

• The citation list or bibliography must be single spaced.
• The last names of the authors must be arranged alphabetically.
• The second line of the source must be indented.

Examples of Citing Different Sources in Chicago Style

Generally, Chicago citations require:

• Title of book/article
• Title of newspaper/journal
• Publication year
• Publication month and date
• City of publication
• Date of access
• Page numbers
• URL or Name of Database

How to Create Footnotes and Endnotes for Chicago Style

If you’re wondering how to format Chicago in-text citations, Notes and Bibliography formatting requires writers to use footnotes and endnotes. These footnotes and endnotes acknowledge the different sources used in the work.

When a source is used in a research paper, a roman numeral is placed at the end of the borrowed information as superscript (it is smaller than the normal line of text and raised). That number correlates with a footnote or endnote.

• Footnotes are found at the bottom of the page
• Endnotes are added at the end of the chapter or project
• A footnote or endnote contains the complete citation information
• The matching number in the footnote or endnote is normal sized and not raised
• It is up to the discretion of the writer to either place the citation at the bottom of the page where the superscript is placed (a footnote) or to place all citations together at the end of the work (endnotes)

One would wonder, "Would young Einstein be characterized as belonging somewhere on the autism spectrum? Would Erdos have been given a diagnosis of A.D.H.D.?" ¹

Chicago style footnotes are placed at the bottom of the page:

• Silver, Nate. "Beautiful Minds." The New York Times. July 13, 2013. Accessed August 04, 2015. http://www.nytimes.com/2013/07/14/books/review/the-boy-who-loved-math-and-on-a-beam-of-light.html?ref=books&_r=0 .

If a source is used more than once in a research project, follow these guidelines:

• When used again, instead of writing out the complete citation for a second time in the footnote, only include: the author’s last name, the title or a phrase for the title (if it’s more than four words), and the page number(s) that were used. This will reduce the bulk of citation information in the paper.
• Cohen, Micah, "Rubio is Losing Support Among Republican Voters." FiveThirtyEight. July 09, 2013. Accessed August 04, 2015. http://fivethirtyeight.com/features/rubio-is-losing-support-among-republican-voters/

• Cohen, "Rubio Losing Support"

If a source is used consecutively, follow these guidelines for shortened citation and ibid :

If you are citing the same source continually throughout your text, use a shortened version of the full citation in your footnotes.

Previous versions of the style used the abbreviation “ibid,” short for “ibidem.” Ibidem is a Latin word that means “in the same place.” It was used when referring to a source that was just cited within a document (without other sources in between). Writers would use ibid instead of writing out the source information again. This was meant to save space since it’s fewer characters than citing the source again.

In the current version of Chicago, the 17th version, ibid is accepted but not preferred. This is because ibid requires readers to go back and search for the previous source cited, an inconvenience which outweighs the benefits of shortening the citation. Also, shortened citations are compact, so using ibid doesn’t always save line space.

Shortened citations

The first mention of a source should include all relevant information (e.g., full author name(s), full title, publisher, date published, etc.).

Subsequent mentions should be a shortened version using this formula:

Last Name, Title of the Work , page number(s).

Mentions after the shortened form can use the abbreviated formula:

Last Name, page number(s).

If there are two or three authors, list their full names in the order they appear in the source. If there are more than three authors, list the first author’s name followed by “et al.”

Examples of using shortened citations (preferred format in the 17th Edition):

• Philip R. Cateora et al., International Marketing (New York: McGraw Hill, 2020), 292-294.
• Cateora et al., International Marketing , 28-29.
• Cateora et al., 28-29.
• Cateora et al., 377.

Long titles that are more than four words are usually shortened. Focus on keeping key words from the title and omitting any beginning “a” or “the.” Examples:

• And to Think That I Saw It on Mulberry Street = Mulberry Street
• Fried Green Tomatoes at the Whistle Stop Cafe = Fried Green Tomatoes

If you are using the discontinued ibid notation, here are a few guidelines:

• When the same source is used consecutively, instead of typing in the citation information again, use the abbreviation “ibid.” Add the page numbers immediately following.
• If the same source AND same page number are used consecutively, simply write “Ibid.”

Same example above, but using ibid:

• Philip R. Cateora et al, International Marketing (New York: McGraw Hill, 2020), 292-294.

Another example with two sources that were mentioned earlier in the text:

• Anthony Doerr, All the Light We Cannot See (New York: Scribner, 2014), 82-84.
• Tatiana de Rosnay, Sarah's Key (New York: St. Martin’s Press, 2007), 24-27.
• Ibid., 133-134.
• Doerr, All the Light We Cannot See , 397-401.
• Ibid., 405.
• Ibid., 411.

Creating Your Citations in Chicago Style

As mentioned, when you're following The Chicago Manual of Style, you'll be required to create a list of all sources used in your paper. Even though full bibliographic information can be found in the footnotes and endnotes, it is still acceptable, and often required by instructors, to create a bibliography. The bibliography is placed at the end of an assignment.

How to Cite a Print Book in Chicago Style

In the bibliography:

Last name, First name. Title of book . Publication Place: Publisher, Year.

Overview of purpose and form of annotated bibliographies from the Purdue OWL.

Includes a sample annotation from a Chicago Manual of Style annotated bibliography. From the Purdue OWL.

An example of an MLA annotated bibliography. From the Purdue OWL.

Assemble your paper in the following order:

• Body of paper
• Appendix (if needed)
• Bibliography

Use Times New Roman, Size 12 (unless otherwise instructed).

Margins and Indents

Your margins should be 1 inch on all sides.

Indent new paragraphs by one-half inch.

Double-space the main text of your paper.

Single-space the footnotes and bibliography, but add a blank line between entries.

Start numbering your pages on the  second  page of your paper (don't include the title page).

Put your page numbers in the header of the first page of text (skip the title page), beginning with page number 1. Continue numbering your pages to the end of the bibliography.

Place the footnote number at the end of the sentence in which you have quoted or paraphrased information from another source. The footnote number should be in superscript, and be placed  after  any punctuation.

Put your footnotes in the footer section of the page.

Your research paper ends with a list of all the sources cited in the text of the paper. This is called a bibliography.

See an example in the "Sample Paper with Bibliography" box on this page.

Here are nine quick rules for this list:

• Start a new page for your bibliography (e.g. If your paper is 4 pages long, start your bibliography on page 5).
• Centre the title, Bibliography, at the top of the page and do not bold or underline it. Look for the alignment option in Word. 
• Leave two blank lines between the title and the first entry on your list.
• Single-space the list, but leave one blank line between entries.
• Start the first line of each citation at the left margin; each subsequent line should be indented (also known as a "hanging indent").
• Put your list in alphabetical order. Alphabetize the list by the first word in the citation. In most cases, the first word will be the author’s last name. Where the author is unknown, alphabetize by the first word in the title, ignoring the words a, an, the.
• For each author, give the last name followed by a comma and the first name followed by a period.
• Italicize the titles of full works , such as: books, videos (films and television shows), artwork, images, maps, journals, newspapers, magazines.
• Do not italicize titles of parts of works , such as: articles from newspapers, magazines, or journals / essays, poems, short stories or chapter titles from a book / chapters or sections of an Internet document. Instead, use quotation marks.

What Is An Annotated Bibliography?

An  annotated bibliography  is a list of citations for various books, articles, and other sources on a topic. The annotated bibliography looks like a Works Cited page but includes an annotation after each source cited. An annotation is a short summary and/or critical evaluation of a source. Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself.

Types of Annotations

 A  summary annotation  describes the source by answering the following questions: who wrote the document, what the document discusses, when and where was the document written, why was the document produced, and how was it provided to the public. The focus is on description. 

 An  evaluative annotation  includes a summary as listed above but also critically assesses the work for accuracy, relevance, and quality. Evaluative annotations can help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project. The focus is on description and evaluation.

• Cite the source using Chicago style.
• Describe the main ideas, arguments, themes, theses, or methodology, and identify the intended audience.
• Explain the author’s expertise, point of view, and any bias he/she may have.
• Compare to other sources on the same topic that you have also cited to show similarities and differences.
• Explain why each source is useful for your research topic and how it relates to your topic.
• Evaluate the strengths and weaknesses of each source.
• Identify the observations or conclusions of the author. 

Remember: Annotations are original descriptions that you create after reading the document. When researching, you may find journal articles that provide a short summary at the beginning of the text. This article abstract is similar to a summary annotation. You may consult the abstract when creating your evaluative annotation, but never simply copy it as that would be considered plagiarism. 

Tips on Writing & Formatting an Annotated Bibliography

• Each annotation should be one paragraph, between three to six sentences long (about 150- 200 words).
• Start with the same format as a regular Bibliography list.
• All lines should be double-spaced. Do not add an extra line between the citations.
• If your list of citations is especially long, you can organize it by topic.
• Try to be objective, and give explanations if you state any opinions.
• Use the third person (e.g., he, she, the author) instead of the first person (e.g., I, my, me)

Chicago In-text Citations | Styles, Format & Examples

Published on September 12, 2019 by Jack Caulfield . Revised on April 9, 2024.

An in-text citation is used to point readers toward any source you quote , paraphrase or refer to in your writing. The Chicago Manual of Style has two options for in-text citations:

• Author-date : you put your citations in parentheses within the text itself.
• Notes and bibliography : you put your citations in numbered footnotes or endnotes.

You should choose one of these two citation options and use it consistently throughout your text. The source details are listed in full in a bibliography or reference list at the end. Make sure to pay attention to punctuation (e.g., commas and quotation marks ).

Which chicago style should you use, option 1: author-date in-text citations, option 2: citations in footnotes or endnotes, citing sources with multiple authors, missing information in chicago in-text citations, frequently asked questions about chicago in-text citations.

First, you need to decide whether you are using notes or author-date in-text citations. You can usually find out from your instructor or syllabus which style you should use.

The notes and bibliography system is usually preferred in humanities subjects like literature, history and the arts. The author-date system is preferred in the sciences, including social sciences.

The styles are similar in the information they present, but they differ in terms of the order, location, and format of that information. It’s important to use one style consistently, and not to confuse the two.

Author-date style places citations directly in the text in parentheses . In-text citations include the author’s last name, the year of publication, and if applicable, a page number or page range:

This style of Chicago in-text citation looks the same for every type of source.

When using author-date, you should always include a reference list  with an entry corresponding to each citation. This provides the reader with full publication information to locate the source.

Where should citations appear in the text?

The author-date style gives you some flexibility in where you place your citations in the text.

Most commonly, you will put the citation at the end of the relevant sentence (before the period). You can also integrate it into the sentence. If you name the author in your sentence, you only need to include the date and page number in parentheses.

Multiple citations can also be combined within one set of parentheses using a semicolon .

As you can see in the Valentine citation, it’s not always necessary to include a page number—only when you’re referring to a specific part of the text. If you want to cite the text as a whole, you can leave out the page number.

In notes and bibliography style, your citations appear in either footnotes or endnotes .

To create a Chicago footnote or endnote reference, a superscript number is placed at the end of the clause or sentence that the citation applies to, after any punctuation (periods, quotation marks , parentheses ). Your first citation is marked with a 1, your second with a 2, and so on.

These superscript numbers correspond to numbered footnotes or endnotes containing the actual citation.

Full notes and short notes

There are two types of note you can use in Chicago style: full and short.

• Full notes contain the full publication details of the source.
• Short notes contain the author’s last name, the title (shortened if it is longer than four words), and the page number (if relevant).

You should usually use a full note the first time you cite each source. If you cite the same source more than once, use a short note for each subsequent citation. You may also use “ ibid. ” to repeat the citation from the previous note, but short notes are the more usual choice.

The rules of your specific institution may vary, requiring you to use one of the two note styles every time. It’s important to check with your instructor if you’re unsure.

This is what a full and short note for the same citation might look like:

The format of the note varies depending on the type of source. Below you can see examples of a Chicago website citation , book citation , book chapter citation , and journal article citation .

Chicago footnote citation examples

• Book chapter
• Journal article

Footnotes or endnotes?

Footnotes appear at the bottom of the page they refer to, while endnotes appear in their own section at the end of the text, before the Chicago style bibliography .

The citation looks exactly the same whether it appears in a footnote or an endnote . If you haven’t been told which one to use, the choice is a matter of personal preference. The important thing is to consistently use one or the other.

In both styles, when you cite a source with two or three authors, list the names in the order they appear in the original publication:

When a source has four or more authors, use the term “ et al. ” after the first author’s name:

Prevent plagiarism. Run a free check.

Sometimes, not all of the information you need for your citation will be available. Thankfully, there are ways to work around this in both styles.

No page number

Page numbers are not always necessary; if the source doesn’t have page numbers (e.g., a website ), or if you’re referring to the general argument of a text instead of a specific passage, you can omit page numbers.

If a source has no page numbers but you still want to specify a particular part of the text, you can use other locators like paragraphs, chapters or headings instead—whatever markers the text provides:

No publication date

If the source doesn’t have a stated publication date, you can write “n.d.” in place of the year:

If no specific author is listed, you can refer to the organization that published the source:

Page numbers should be included in your Chicago in-text citations when:

• You’re quoting from the text.
• You’re paraphrasing a particular passage.
• You’re referring to information from a specific section.

When you’re referring to the overall argument or general content of a source, it’s unnecessary to include page numbers.

When a source has four or more authors , your in-text citation or Chicago footnote should give only the first author’s name followed by “ et al. ” (Latin for “and others”). This makes your citations more concise.

In your bibliography or reference list , when a source has more than 10 authors, list the first seven followed by “et al.” Otherwise, list every author.

• 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.

In Chicago notes and bibliography style , the usual standard is to use a full note for the first citation of each source, and short notes for any subsequent citations of the same source.

However, your institution’s guidelines may differ from the standard rule. In some fields, you’re required to use a full note every time, whereas in some other fields you can use short notes every time, as long as all sources are listed in your bibliography . If you’re not sure, check with your instructor.
