What is Chicago Author-Date Style?
Chicago is a documentation style 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 Chicago Style.
For information about the Notes and Bibliography style preferred by many arts and humanities disciplines, please see the Chicago Notes & Bibliography style page.
