Chicago Citation Style 17th Edition

This guide will help you cite sources in Chicago Citation Style 17th Edition.

Chicago-Style Citation Quick Guide

Guidelines for Building a Citation

Numbers in parentheses refer to specific pages in The Chicago Manual (17th ed.) 

Each entry in your Bibliography usually contains the following information, in this order: author(s) or editor(s), title of work, and facts of publication.

There are specific rules around the formatting of each part of the citation. The general format for a book is given below; refer to The Chicago Manual of Style for more information. Other types of sources will include different citation elements.

Author or Editor Information (pp. 784-91)

Author's names are given as they appear on the title page (p. 785). In the Bibliography, invert the order of the first author's names (e.g. last name first) so that they will appear correctly in the alphabetical list. Subsequent authors and editors may be written normally, without inverting the first and last name (p. 786).  

E.g. Elms, Jack, and Lauren D. Curtis. 

If there is no author, begin the entry with the title, ignoring any introductory articles (e.g. The, A, An) (p. 787).

In a reference to an edited book, insert the editor's name in place of the author's name, followed by a comma and the abbreviation "ed." (without the quotation marks) (pp. 800-801).

Title of Work (pp. 791-99)

Capitalize first and last words in titles and subtitles, and capitalize all other major words (p. 792).

Titles and subtitles of books and periodicals are italicized (p. 791).

Arrange your Bibliography in one alphabetical sequence by the surname of the author, or by title or keyword if there is no author (p. 777).

For an edition other than the first, identify the edition of your source by number (e.g. 2nd ed.) or by name (e.g. Rev. ed. for "revised edition") (p. 806). The edition statement usually comes after the title of the work (p. 806).

Facts of Publication (city, publisher, date, {medium/format}) (pp. 813-21)

List the location, publisher’s name, and year of publication as they appear on the title page or copyright page. If there is more than one city, list the first one only (p. 813).

If the city of publication is not well known or it could be confused with another city in a different location, it may be useful to include an abbreviation of the state, province, or country (pp. 813-14). 

If no date is available, use the abbreviation n.d. (p. 820).

For electronic sources include a URL or DOI.
