IPH 207C: Modern Political Thought (Koellner)

The Chicago Manual of Style actually presents two different styles of documentation and citation: the humanities style, which uses notes and a bibliography, and the author-date system. As the name suggests, humanities style is more common for writing in the arts, literature, and related disciplines, while author-date is found more frequently, though not exclusively, in the natural and social sciences. 

Developed by the Modern Language Association, this style is widely used in literary studies and throughout the humanities. Unlike Chicago humanities style, it uses in-text citations rather than notes.
