An APA style guide can be found at the Online Writing Lab (OWL). You can access this from the MC3 library Help Zone.
OWL provides the following as the basic format for books:
Author, A. A. (Year of publication). Title of work: Capital letter also for subtitle. Location: Publisher.
Note: For "Location," you should always list the city and the state using the two letter postal abbreviation without periods (New York, NY).
