Introduction

The Chicago Manual of Style (CMOS) covers a variety of topics from manuscript preparation and publication to grammar, usage, and documentation, and as such, it has been lovingly dubbed the “editor's bible.”

The material on this page focuses primarily on one of the two CMOS documentation styles: the Notes-Bibliography System (NB) , which is used by those working in literature, history, and the arts. The other documentation style, the Author-Date System, is nearly identical in content but slightly different in form and is preferred by those working in the social sciences.

Though the two systems both convey all of the important information about each source, they differ not only in terms of the way they direct readers to these sources, but also in terms of their formatting (e.g., the position of dates in citation entries). For examples of how these citation styles work in research papers, consult our sample papers:

In addition to consulting The Chicago Manual of Style (17th edition) for more information, students may also find it useful to consult Kate L. Turabian's Manual for Writers of Research Papers, Theses, and Dissertations (8th edition). This manual, which presents what is commonly known as the "Turabian" citation style, follows the two CMOS patterns of documentation but offers slight modifications suited to student texts.

Notes and Bibliography (NB) in Chicago style

The Chicago Notes and Bibliography (NB) system is often used in the humanities to provide writers with a system for referencing their sources through the use of footnotes, endnotes, and through the use of a bibliography. This offers writers a flexible option for citation and provides an outlet for commenting on those sources, if needed. Proper use of the Notes and Bibliography system builds a writer’s credibility by demonstrating their accountability to source material. In addition, it can protect writers from accusations of plagiarism, which is the intentional or accidental uncredited use of source material created by others.

Introduction to Notes

In the Notes and Bibliography system, you should include a note (endnote or footnote) each time you use a source, whether through a direct quote, paraphrase, or summary. Footnotes are added at the end of the page on which the source is referenced, while endnotes are compiled at the end of each chapter or at the end of the entire document.

In either case, a superscript number corresponding to a note, along with the bibliographic information for that source, should be placed in the text following the end of the sentence or clause in which the source is referenced.

If a work includes a bibliography, which is typically preferred, then it is not necessary to provide full publication details in notes. However, if a bibliography is not included with a work, the first note for each source should include all relevant information about the source: author’s full name, source title, and facts of publication. If you cite the same source again, or if a bibliography is included in the work, the note only needs to include the surname of the author, a shortened form of the title (if more than four words), and the page number(s). However, in a work that does not include a bibliography, it is recommended that the full citation be repeated when it is first used in a new chapter.

In contrast to earlier editions of CMOS, if you cite the same source two or more times consecutively, CMOS recommends using shortened citations. In a work with a bibliography, the first reference should use a shortened citation which includes the author’s name, the source title, and the page number(s), and consecutive references to the same work may omit the source title and simply include the author and page number. Although discouraged by CMOS, if you cite the same source and page number(s) from a single source two or more times consecutively, it is also possible to utilize the word “Ibid.,” ( from the Latin ibidem, which means “in the same place,”) as the corresponding note. If you use the same source but a draw from different new page, the corresponding note should use “Ibid.” followed by a comma and the new page number(s).

In the NB system, the footnote or endnote itself begins with the appropriate full-sized number, followed by a period and then a space.

Introduction to Bibliographies

In the NB system, the bibliography provides an alphabetical list of all sources used in a given work. This page, most often titled Bibliography, is usually placed at the end of the work preceding the index. It should include all sources cited within the work and may sometimes include other relevant sources that were not cited but provide further reading.

Although bibliographic entries for various sources may be formatted differently, all included sources (books, articles, websites, etc.) are arranged alphabetically by author’s last name. If no author or editor is listed, the title or, as a last resort, a descriptive phrase may be used.

Though useful, a bibliography is not required in works that provide full bibliographic information in the notes.

Common Elements

All entries in the bibliography will include the author (or editor, compiler, translator), title, and publication information.

Author Names

The author’s name is inverted in the bibliography, placing the last name first and separating the last name and first name with a comma; for example, John Smith becomes Smith, John.

Titles of books and journals are italicized. Titles of articles, chapters, poems, etc. are placed in quotation marks .

Publication Information

The year of publication is listed after the publisher or journal name .

Punctuation

In a bibliography, all major elements are separated by periods.

For more information and specific examples, see the sections on Books and Periodicals .

Please note that this OWL resource provides basic information regarding the formatting of entries used in the bibliography. For more information about Selected Bibliographies, Annotated Bibliographies, and Bibliographic Essays, please consult Chapter 14.61 of The Chicago Manual of Style (17th edition).

Writing Tips

How to Write and Format a Chicago Style Paper [With Examples]

3-minute read
18th August 2023

Are you working on a Chicago style project but struggling with the question, “just what is it?!”

Fear not, this post will walk you through Chicago style basics.

What Is Chicago Style?

The Chicago Manual of Style (CMoS) is a comprehensive style guide primarily used by professional writers, publishers, and researchers. It covers various forms of writing, including books, journals, magazines, and other publications. It’s often the go-to style for publishers and editors. CMoS is also known for its emphasis on scholarly writing and is suitable for a wide range of disciplines, including history, literature, the arts, and social sciences.

However, there’s an important distinction between Chicago style and Turabian style , which is essentially a simplified version of CMoS used in scholarly writing. Turabian omits some of the complexities and focuses on the needs of academic writers, especially those in the humanities and social sciences.

With either style, it’s essential to consult the relevant edition of the style guide specified by your institution or publication: either The Chicago Manual of Style or A Manual for Writers by Kate L. Turabian (currently in its ninth edition).

How Are Chicago Style Citations Formatted?

CMoS emphasizes two primary documentation systems : the notes and bibliography system (often used in the humanities) and the author–date system (preferred in the sciences and social sciences). When formatting a CMoS/Turabian paper, you’ll need to adhere to the guidelines associated with your chosen documentation system.

Notes and Bibliography System:

● In this system, you’ll use footnotes or endnotes to cite sources within the text.

● A corresponding bibliography is included at the end of the paper, listing all sources in alphabetical order.

● Citations typically include author names, titles, publication details, and page numbers.

Author–Date System:

● In the author–date system, you’ll incorporate in-text citations within parentheses.

● A reference list is included at the end of the document, providing full details for each cited source.

● Citations include author’s last names, publication year, and page numbers (if applicable).

What Does Turabian Style Formatting Look Like?

A well-structured Turabian Style paper should adhere to the following formatting guidelines :

Title page : Include the title of your paper, your name, the course name/number, instructor’s name, and the date on a separate page, starting a third of the page down. Alternatively, write the title on the first page.
Margins : Apply one-inch margins on all sides.
Indentation and spacing : Indent paragraphs and double-space the main text.
Font : Use a legible 12-point font (e.g., Times New Roman).
Page numbers : Number all pages consecutively in the top right corner, starting with the first page. Alternatively, page numbers may be placed at the bottom center of the page.
Headings and subheadings : Use headline-style capitalization for headings and subheadings, with different levels distinguished.
Footnotes or in-text citations: Implement your chosen citation system consistently throughout the paper.
Bibliography or reference list : Include a comprehensive list of all sources used, following Chicago style citation guidelines for your chosen system.

How Should I Choose Which Chicago Style Documentation to Use?

It’s crucial to find out which specific CMoS system is preferred by your institution, publisher, or field of study. Always consult your assignment guidelines or style manual to determine whether you should use the notes and bibliography system or the author–date system. This choice will significantly impact how you format your citations and references.

Remember that mastering CMoS takes practice. By following these guidelines, you’ll be well on your way to crafting polished, professionally formatted papers that meet the expectations of your academic or professional audience.

Citing sources with notes (notes and bibliography), chicago note citation examples (notes and bibliography), creating a chicago style bibliography (notes and bibliography), chicago author-date style, frequently asked questions about chicago style citation.

To cite sources in Chicago notes and bibliography style, place a superscript number at the end of a sentence or clause, after the punctuation mark, corresponding to a numbered footnote or endnote .

Footnotes appear at the bottom of each page, while endnotes appear at the end of the text. Choose one or the other and use it consistently.

Most word-processing programs can automatically link your superscript numbers and notes.

Full notes vs. short notes

Citations can take the form of full notes or short notes. Full notes provide complete source information, while short notes include only the author’s last name, the source title, and the page number(s) of the cited passage. The usual rule is to use a full note for the first citation of each source, and a short note for subsequent citations of the same source.

Guidelines can vary across fields, though; sometimes you might be required to use full notes every time, or conversely to use short notes every time, as long as all your sources are listed in the bibliography. It’s best to check with your instructor if you’re unsure which rule to follow.

Multiple authors in Chicago notes

When a source has multiple authors, list up to three in your note citations. When there are four or more, use “ et al. ” (Latin for “and others”).

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

A Chicago footnote or endnote citation always contains the author’s name and the title of the source. The other elements vary by the type of source you’re citing.

Page number(s) should be included if you are referring to a specific part of the text. The elements of the citation are separated by commas , and the note always ends with a period. The page range is separated by an en dash .

Navigate through the Chicago citation examples using the tabs below.

Book chapter
Journal article

When citing a book , if an edition is specified, include it in abbreviated form (e.g., 2nd ed.). If the book was accessed online, add a URL.

Full note	Author full name, , edition. (Place of publication: Publisher, Year), page numbers, URL.
Short note	Author last name, , page number(s).

When citing a chapter from a multi-authored book, start with details of the chapter, followed by details of the book.

Full note	Author full name, “Chapter Title,” in , ed. Editor full name (Place of publication: Publisher, Year), page number(s).
Short note	Author last name, “Shortened Chapter Title,” page number(s).

To cite a journal article , you need to specify the volume and issue as well as the date. It’s best to use a DOI instead of a URL.

Chicago Journal article citation example

Full note	Author full name, “Article Title,” Volume, no. Issue</span? (Year): page number, DOI/URL.
Short note	Author last name, “Shortened Article Title,” page number(s).

Web pages often have no author or date specified. If the author is unknown, start with the title in a full note, and use the website name as author in a short note. If the publication date is unknown, include the date you accessed the information (e.g., accessed on March 12, 2022).

Full note	Author full name, “Page Title,” Website Title, Month Day, Year, URL.
Short note	Author last name, “Shortened Page Title.”

The bibliography lists full references for all your sources. It appears at the end of your paper (before any appendices ).

Author names are inverted in the bibliography, and sources are alphabetized by author last name. Each source is listed on a new line, with a hanging indent applied to sources that run over onto multiple lines.

If a source has multiple authors, list up to 10 in the bibliography. If there are 11 or more, list the first seven followed by “et al.”

When to include a bibliography

It is not mandatory to include a bibliography if you have cited your sources with full notes. However, it is recommended to include one in most cases, with the exception of very short texts with few sources.

Check with your instructor if you’re not sure whether to include one.

Chicago style bibliography examples (notes and bibliography)

Bibliography entries vary in format according to source type. Formats and examples for some common source types are shown below.

Format	Author last name, first name. . Edition. Place of publication: Publisher, Year. URL.
Example	Covey, Stephen. . New York: Free Press, 1989.

Format	Author last name, first name. “Chapter Title.” In , edited by Editor first name last name, page range. Place of publication: Publisher, Year.
Example	Stewart, Bob. “Wag of the Tail: Reflecting on Pet Ownership.” In , edited by John Jaimeson, 220–90. Toronto: Petlove Press, 2007.

Format	Author last name, first name. “Article Title.” Volume, no. Issue (Month Year): Page range. DOI/URL.
Example	Datta, Hannes. “The Challenge of Retaining Customers Acquired with Free Trials.” 52, no. 52 (April 2015): 217–34. www.jstor.org/stable/43832354.

Format	Author last name, first name. “Page Title.” Website Name. Month Day, Year. URL.
Example	Caulfield, Jack. “How To Do Thematic Analysis.” Scribbr. September 6, 2019. https://www.scribbr.com/methodology/thematic-analysis/.

In the (social) sciences, you may be told to use author-date style instead. In this style, citations appear in parentheses in the text.

Unlike note citations, author-date citations look the same for all source types .

Reference list

Author-date citations are always accompanied by a reference list. The reference list is similar to a bibliography: It appears at the end of your text and lists all your sources in full.

The only difference is that the publication year comes straight after the author name, to match with the in-text citations. For example, the book reference from above looks like this in author-date style.

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.”

	Full note	Short note	Bibliography
2 authors	Anna Burns and Robert Smith	Burns and Smith	Burns, Anna, and Robert Smith.
3 authors	Anna Burns, Robert Smith, and Judith Green	Burns, Smith, and Green	Burns, Anna, Robert Smith, and Judith Green.
4+ authors	Anna Burns et al.	Burns et al.	Burns, Anna, Robert Smith, Judith Green, and Maggie White.

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.

Type	Example
Full note	1. “An Introduction to Research Methods,” Scribbr, accessed June 11, 2020, https://www.scribbr.com/category/methodology/.
Short note	2. Scribbr, “Research Methods.”
Bibliography	Scribbr. “An Introduction to Research Methods.” Accessed June 11, 2020. https://www.scribbr.com/category/methodology/.

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.”

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.

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.

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.
