Who Should Use Chicago Citation Style?

The Chicago Style is used in both the humanities and social sciences. 

There are two documentation systems within the Chicago Style: the humanities style and the author-date system.  The humanities style is preferred by many in literature, history and the arts. The author-date system is more precise and generally used by the physical, natural and social sciences. Choosing which of these systems is most appropriate often depends on the subject matter and the type of sources being cited.

Disciplines Using Chicago Style Include But Are Not Limited to:

  • Business

  • Library Science
  • Publishing fields [sometimes Journalism]
