How to cite a PhD thesis in Chicago

Chicago style PhD thesis citation

To cite a PhD thesis in a reference entry in Chicago style 17th edition include the following elements:

  1. Author(s) of the thesis: Give first the last name, then the name as presented in the source (e. g. Watson, John). For two authors, reverse only the first name, followed by ‘and’ and the second name in normal order (e. g. Watson, John, and John Watson). For more than seven authors, list the first seven names followed by et al.
  2. Title of the thesis: Give the title in quotation marks.
  3. Degree: Type of degree.
  4. University: Give the name of the institution.
  5. Year of publication: Give the year of publication as presented in the source.

Here is the basic format for a reference list entry of a PhD thesis in Chicago style 17th edition:

Author(s) of the thesis. "Title of the thesis." Degree, University, Year of publication.
