Citation Style Guides

NEW! The 18th edition of the Chicago Manual of Style was published in September 2024. Here's what's changed since the 17th edition. Check with your professor if they have a preference between the 17th and 18th editions.

Chicago Style offers two ways of citing your sources:

• Author-Date: Similar to MLA and APA style, you put the author and date of publication in parentheses in your text, and then you put the full citation in a References section at the end of your paper.
• Notes and Bibliography: You cite your source in a numbered footnote or endnote, and then you put the full citations in a slightly different format in a Bibliography section at the end of your paper.

See the tabs below for guidance on each method, or view the full Chicago Manual of Style online through the Library.

Kate L. Turabian's Manual for Writers of Research Papers, Theses, and Dissertations follows the two Chicago Manual of Style patterns of documentation but offers slight modifications suited to student texts.

Also, A Pocket Guide to Writing History (8th edition), also known as "Rampolla," is available in the Reference section on the first floor of the Library (Ref 907.2 R148a).  This writing guide uses Turabian style.

From the AAA website: "As of September 2015, AAA style (for all publications) follows the Chicago Manual of Style, 17th edition, particularly in regard to reference citations."
