Chicago Citation Guide - 17th Edition

A guide to using Chicago Manual of Style, 17th Edition


Author-Date is one of the two formats for the Chicago citation style. Author-Date has two main components:

  1. References listed in a references list or bibliography. These references will all have the date component second.
  2. In-text citations within the paper, referring back to the references list/bibliography.


Format your references list as follows:

  • Arrange citations alphabetically by author.
  • Leave 2 blank lines between your "References" heading and the first citation
  • Single space all citations.
  • Double space between all citations.
  • Format all citations with a hanging indent.

If using multiple resources by the same author, use a 3-em dash (———) after the first instance of the name:
