Chicago Style: Home

The Chicago Manual of Style is often used to document sources for papers and assignments in the Humanities (e.g., history, fine arts, philosophy, and political science). Check with your instructor to determine which citation style you should use for an assignment.

The Chicago Manual of Style released the 18th Edition of the style manual in September 2024. Chicago has two formats for referencing: Notes and Bibliography (sometimes called Notes or Chicago A) and Author-Date (sometimes called Chicago B).

Check with your lecturer which edition of the style you should be using.

The purpose of using citations is to let the reader know where you obtained your information so sources can easily be located and consulted. You must document your sources when you provide information that you ordinarily would not have known before conducting your research.

You must cite when you:

• Discuss or paraphrase someone else's ideas
• Provide a direct quotation
• Use statistical or other data

 The Chicago Manual of Style Online provides some brief information and examples of this form of citation. 

The OWL at Purdue provides useful resources and sample citations in Chicago Style. 

You can also find information about Chicago Style at the University of Wisconsin - Madison Writing Center.
