Citation Guide: Chicago Manual of Style (Author/Date System)
The Chicago Manual of Style documentation system is used in both the humanities and the social sciences. A bit more complex than either the MLA or the APA, it offers two approaches for documenting sources: 1) a notes system and, 2) an author/date system similar to the APA. This guide explains the Author/Date system. A separate guide explains the Chicago Manual of Style (Notes System).
Inserted at the point of reference, an in-text parenthetical citation containing the author's name and the date of publication interacts with the end documentation by pointing to a specific entry on the References List page.
Notes, similar to those used in the CMS Notes System, may be used in the Author/Date system, but only to provide further information about a particular idea. They do not replace entries found in the References List which contains the bibliographic information required to properly cite your sources. Check with your instructor on what is expected when you are asked to use this style.
This guide is largely based on style recommendations from the 14th edition of the Chicago Manual of Style, however, you may also wish to consult the 6th edition of Kate Turabian's A Manual for Writers of Term Papers, Theses, and Dissertations. In it you will find many corresponding or similar documentation patterns.
