The Chicago Manual of Style is often used in history and other humanities, and in the social sciences. There are two types of Chicago style: 1. notes and bibliography, and 2. author-date. If your instructor has asked you to use endnotes or footnotes, you will be using the notes and bibliography format. The author-date format uses parenthetical citations within the text of your paper.
