What is Chicago Style?

Chicago Style isn’t just a deep dish pizza. Originally published in 1906, the Chicago Style Manual is now in its 16th edition. It was essentially written as a reference for authors, editors, copywriters, publishers, and other areas where the written word is primarily used. It’s now used by other disciplines as well.

There are two Chicago Manual Styles: Notes-Bibliography System and Author-Notes System.


  • Notes-Bibliography System is often used in literature, history, and the arts
  • Author-Notes System is often used in the social sciences
