Chicago Manual of Style


It is often sufficient simply to describe web pages and other website content in the text (“As of May 1, 2017, Yale’s home page listed . . .”). If a more formal citation is needed, it may be styled like the examples below. For a source that does not list a date of publication or revision, include an access date (as in example note 2).


1. “Privacy Policy,” Privacy & Terms, Google, last modified April 17, 2017,
