Chicago Citation Style

This guide will help you cite sources using the Chicago Citation Style 16th edition.

Secondary Sources (14.273 / p. 764)

Sometimes an author will quote work someone else has done, but you are unable to track down the original source. In this case, both the original and the secondary source must be listed in the note and the bibliography. 

   
If, for example, you were reading a book and the author of the book (in the example below, that would be Sarah Gwyneth Ross) made reference to the work done by another author (in the example below, that would be Astrik L. Gabriel), you would refer to the work as per the layout below.
