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
  • History
  • Library Science
  • Publishing fields [sometimes Journalism]

The ASU Library acknowledges the twenty-three Native Nations that have inhabited this land for centuries. Arizona State University's four campuses are located in the Salt River Valley on ancestral territories of Indigenous peoples, including the Akimel O’odham (Pima) and Pee Posh (Maricopa) Indian Communities, whose care and keeping of these lands allows us to be here today. ASU Library acknowledges the sovereignty of these nations and seeks to foster an environment of success and possibility for Native American students and patrons. We are advocates for the incorporation of Indigenous knowledge systems and research methodologies within contemporary library practice. ASU Library welcomes members of the Akimel O’odham and Pee Posh, and all Native nations to the Library.
