Chicago documentation style (Doc. 11)

In Chicago style, superscript numbers in the text of the paper refer readers to notes with corresponding numbers either at the foot of the page (footnotes) or at the end of the paper (endnotes). A bibliography is often required as well; it appears at the end of the paper and gives publication information for all the works cited in the notes.

The guidelines presented here are consistent with advice given in The Chicago Manual of Style, 16th ed. (2010).

TEXT

A Union soldier, Jacob Thompson, claimed to have seen Forrest order the killing, but when asked to describe the six-foot-two “a little bit of a man.”12

FOOTNOTE OR ENDNOTE

Bottom of Form

First and subsequent notes for a source

The first time you cite a source, the note should include publication information for that work as well as the page number on which the passage being cited may be found.

1. Peter Burchard, One Gallant Rush: Robert Gould Shaw and His Brave Black Regiment (New York: St. Martin’s, 1965), 85.

For subsequent references to a source you have already cited, you may simply give the author’s last name, a short form of the title, and the page or pages cited. A short form of the title of a book is italicized; a short form of the title of an article is put in quotation marks.

4. Burchard, One Gallant Rush, 31.

When you have two consecutive notes from the same source, you may use “Ibid.” (meaning “in the same place”) and the page number for the second note. Use “Ibid.” alone if the page number is the same.

5. Jack Hurst, Nathan Bedford Forrest: A Biography (New York: Knopf, 1993), 8.

6. Ibid., 174.

Chicago-style bibliography

A bibliography, which appears at the end of your paper, lists every work you have cited in your notes; in addition, it may include works that you consulted but did not cite. For advice on constructing the list, click here. For a sample bibliography click here.

NOTE: If you include a bibliography, The Chicago Manual of Style suggests that you shorten all notes, including the first reference to a source, as described on this page. Check with your instructor, however, to see whether using an abbreviated note for a first reference to a source is acceptable.

Model notes and bibliography entries

The following models are consistent with guidelines set forth in The Chicago Manual of Style, 16th ed. (2010). For each type of source, a model note appears first, followed by a model bibliography entry. The note shows the format you should use when citing a source for the first time. For subsequent citations of a source, use shortened notes.

Some online sources, typically periodical articles, use a permanent locator called a digital object identifier (DOI). Use the DOI, when it is available, in place of a URL in your citations of online sources.

When a URL (Web address) or a DOI must break across lines, do not insert a hyphen or break at a hyphen if the URL or DOI contains one. Instead, break the URL after a colon or a double slash or before any other mark of punctuation.
