Reference materials may provide definitions, facts and userful background and overview information on your topic. Below is a list of selected reference titles available through the Moorpark College Library Catalog. All of the print reference sources are located on the second floor of the Library in the reference area. On the Library Search page are two great online reference databases: Gale eBooks and Credo Reference. Use the Databases A-Z to access these databases. To access the databases from off campus, login to MyVCCCD with your username and password.
