Chicago Manual of Style

The Oregon Tech Library provides this abbreviated guide to documentation of sources for academic and professional writings. The guide is based on The Chicago Manual of Style, 16th ed. Chicago: University of Chicago Press, 2010. The manual is located in the reference section of the Library. Look for it by its call number: REF Z253 .U69 2010.

Citing Sources in Chicago Style

The two citation systems of the Chicago citation style are widely used in academic institutions; the choice between the two is based on a specific discipline and subject.

  • The notes and bibliography system is used for citing sources in literature, history and the arts
  • The author-date system is used for citing sources in physical, natural, and social sciences

Due to its lack of use on campus, the notes and bibliography system is not included in this guide. If you want to know more about this system see The Chicago Manual of Style, Chapter 14, pages 653–784.

For additional information on both systems visit the Chicago citation style website. It should be consulted for updates on citation formats, especially for documenting electronic sources. Online help of the entire manual from the website is available with a paid subscription.
