Call Numbers are basically a book's address.  NOVA Libraries uses the Library of Congress Call Number System, which is the same system used in most college and university libraries.  It organizes books by subject using an alpha numeric code. 

When you find a book in the Library Catalog, look for and write down its Call Number.  E.g., QA29.H88 D43 2007.
