Citation, Documentation of Sources
Q. I found some phone conversations between Richard Nixon and some other people in office, and I’m not sure how to cite them. Should I cite the transcript and include the website that they came from, too? They came from the National Security Archive, George Washington University.
A. Yes, cite the transcript and give the name and URL of the website where you found them. You can find examples to follow at CMOS 14.211 and 14.229.
