Chicago Style


Chicago document formatting

When setting up your word processor for an Chicago-formatted document, use the following settings to format your page:

Chicago Page Formatting

  • Use one-inch margins on all sides of the document.

  • Place the page number on the right side of each page in the document’s header. If instructed to do so by a professor, include your last name before the page number on each page.

  • Double space the document.

  • Block quotes are formed when a quote runs more than 100 words. Indent the entire block of text with a 1/2-inch tab from the left margin.

  • Endnotes and bibliographic entries are single-spaced with a blank line separating them.

  • Indent the first line of a note entry with a 1/2-inch tab.

  • Indent the second, and any subsequent, line of a bibliographic entry with a 1/2-inch tab.

  • The Chicago form requires a title page. The title of the essay is centered about 1/3 down the top of the page. Place your name, course information, and date on three separate, centered lines at the center of the document.

  • The title page is counted but not numbered. This means that the first page of your essay proper will be numbered 2 and your title page will have no page number on it.

Example:

Chicago Notes page formatting

The Chicago style has two ways of approaching citation. In one method, known as author-date, references are placed in the text within a parenthesis using the author’s last name and the year of the source’s publication. The author-date method is common in the sciences and social sciences. A second method is known as notes and bibliography. In this method, in-text citations are made using either footnotes, which appear at the bottom of a page, or endnotes, which appear on a separate Notes page at the conclusion of the document. This handbook only presents the notes and bibliography method with endnotes.

To set up your Notes page properly, follow the rules below:

Formatting the Notes page

Setting up the Notes page

When setting up the Notes page, use the following rules:

  • Center the word “Notes” at the top of the page.

  • Place the page number on the right side of each page in the document’s header. If instructed to do so by a professor, include your last name before the page number on each page.

  • Single-space the endnotes with a line separating entries.

  • Indent the first line of an endnote entry with a 1/2-inch tab.

Making endnote or footnote entries

When making footnote or endnote entries, the Chicago form prescribes a specific strategy designed to lessen the work involved. While this design ultimately means less typing, a number of strict rules must be followed:

  • Present the citations in the numerical order as they appear within the text.

  • The first time a source is cited, use the full Chicago notes form.

  • If the same source is used more than once, the shorthand version of the Chicago notes form is used the second (and each subsequent) time. The shorthand version contains a) the author’s last name, b) a shortened version of the title, and c) the page number(s) of the citation.

  • If a source is used twice (or more) in a row, the Latin abbreviation “Ibid.” is used along with the page number, rather than the shorthand version of the form. (Ibid. means “in the same place.”)

  • If a source is used twice (or more) in a row and the citation is from the same page, “Ibid.” is used by itself without the page number.

Example:

Chicago Bibliography page formatting

The Chicago style does not require that you include a bibliography page at the conclusion of your essay; the Notes page is often sufficient unless the work is very long or contains a large number of citations. However, your professor may require one. To construct a Chicago bibliography, follow the rules below:

Formatting the Bibliography page

Setting up the Bibliography page

To format a Chicago bibliography page, use the following rules:

  • Place the bibliography page after the notes page.

  • Place the page number on the right side of each page in the document’s header. If instructed to do so by a professor, include your last name before the page number on each page.

  • Center the word “Bibliography” at the top of the page.

  • Single-space entries with a line separating entries.

  • Alphabetize by the author’s last name.

  • Indent the second (and any subsequent) line of an entry with a 1/2-inch tab.

Example:

Chicago in-text citations

When using Chicago’s notes and bibliography method of citation, in-text citations are made using either footnotes, which appear at the bottom of a page, or endnotes, which appear on a separate “Notes” page at the conclusion of the document. This handbook exclusively presents the notes and bibliography method using endnotes.

Chicago in-text citations

In-text citations

In the Chicago form, an in-text citation is indicated by a superscript number resembling the following:

Recent scholarship on the concept of sovereignty has displayed a remarkable lack of interest in Native peoples.7

This in-text reference will correspond to either a footnote at the bottom of the page or an endnote on the Notes page at the conclusion of the document. The reference will resemble the one below:

7. Giorgio Agamben, Homo Sacer: Sovereign Power and Bare Life (Stanford: Stanford University Press, 1998), 96.

Citing your sources in Chicago

The following section provides examples for citing sources that are commonly found in academic writing. Both the Notes and Bibliography forms are included. The various forms have been organized into sections on books, periodicals, electronic sources, and other types of sources that are less common.

Citing Online sources

Online Forms

The Chicago form prefers that citations of online sources use a DOI (Digital Object Identifier). A DOI is a long string of numbers and letters that provide a unique identifier for an online object, such as an article or book. However, many online objects do not have a DOI. In that case, the Chicago form asks you to use a stable URL. If no stable URL is available, and the URL for your source is very long, you may shorten it to include only the domain name.

Article in an online database:

Bibliography

Taylor, Hayden. “Moby Dick and the Cold War.” American Literature 45, no. 6 (2010): 45-57. doi: 12.2398/ahl.483.1.112.

Notes

22. Hayden Taylor, “Moby Dick and the Cold War,” American Literature 45, no. 6 (2010): 45-57. doi: 12.2398/ahl.483.1.112.

  • Cite the source as you would a print article then include the DOI or stable URL. If neither exists, end the citation with the database name.

A work from a website:

Bibliography

Reagan, John. “The Judo Champion Parent.” Parenthood Online. The Parent Institute of Boston. Accessed October 5, 2011. http://www.pibonline.org/10-5-reg.

Notes

17. Reagan, John, “The Judo Champion Parent,” Parenthood Online, The Parent Institute of Boston, accessed October 5, 2011. http://www.pibonline.org/10-5-reg.

  • If there is no author listed, use the name of the publication’s sponsor as the author and do not not repeat the sponsor after the name of the website.

Article in an online reference work, such as Wikipedia:

Notes

8. Wikipedia, s.v. “Iraq,” last modified May 1, 2013, http://en.wikipedia.org/wiki/Iraq.

  • Well-known reference sources, such as encyclopedias or dictionaries, that are arranged alphabetically by word or arranged by term do not require page numbers. Abbreviate the Latin term sub verbo, or “under the word,” in your note to indicate this. Additionally, sources like these do not need to be included in your bibliography; including the source in your Notes page is sufficient.
