Search OneSearch for books and other library materials by keyword (recommended). If you're looking for a specific item you can search by title, author, etc.
For tips on searching OneSearch, see the OneSearch guide at https://libguides.calstatela.edu/c.php?g=955926&p=6899064
When you find one book in the library catalog that looks useful, review the subject terms that are listed in the book's record. Click on the link for any subject term that looks relevant to view other books in the library also on that subject.
