Q. Do I have to include both the city and state in a reference to a book?
Yes, in the sixth edition of the APA publication style, you are required to include both the city and state in the publication information part of a book reference. If a book was printed in the United States, use the first US city listed on the title page and follow it with the state abbreviation.
Los Angeles is the first US city listed on the following title page:
The publication information section in a reference to this book would be:
Los Angeles, CA: Sage.
