What is Chicago Author-Date Style?

Chicago is a documentation syle that has been published by the Chicago University Press since 1906. The Author-Date style (sometimes referred to as "Reference List" style) is recommended for the physical, natural, and social sciences. Sources are cited using parenthetical in-text citation and full details are provided in a reference or works cited list.

"Turabian" style, widely used for decades by students, is essentially a simplified version of the Chicago Manual.

This page provides examples of entries for the Author-Date style (Chicago Manual, 17th edition, and Turabian Manual, 9th edition), as well as links to other sources and examples. For examples of the Notes and Bibliography style preferred by many in humanities disciplines, including history, literature, and the arts, please see the Chicago Notes & Bibliography style page.
