Chicago Style

This information is taken from

Please visit this helpful, easy to use site if you need additional information about the Chicago formatting style.

The Chicago Manual of Style presents two documentation systems:

  • the humanities style, which utilizes notes and a bibliography
  • the author-date system, which utilizes brief in-text citations and a list of references

If you are uncertain which system to use, you should ask your professor if he/she has a preference.  However, choosing a system also depends on what academic discipline you are studying.  The humanities style is typically used by students in literature, history and the arts.  The author-date system has long been used by people in the physical, natural and social sciences.
