Author-Date Citation Style

Citing Sources with Author-Date Citation Style

The CMS Author-Date citation style is predominantly used in the sciences. This citation style uses an in-text citation with author last name and year of publication, which corresponds to a full source citation in a bibliography. Please always check your course materials and/or ask your professor which CMS citation style to use.
