How do I read call numbers?

Call numbers serve several purposes. A call number is like an address; it describes the exact location of the book and tells where to find the book on the shelves. Each book in the library has a unique call number. Call numbers also group books on similar subjects together so once you've found a book you can browse other books on the same subject. The WSU Libraries use several kinds of call numbers and each system uses letter codes to organize materials.

Paul Laurence Dunbar Library uses the Library of Congress (LC) system:

Fordham Health Sciences Library uses the National Library of Medicine (NLM) system:

The government documents collection uses the Superintendent of Documents (SuDocs) system:

Call numbers and location codes work together to give you the exact location of books, journals, and other material. For more help read Where do I look for this location?
