Library of Congress Classification System (LC)

This Library, along with most other academic libraries, uses the Library of Congress (or L.C.) classification system, which arranges books by subject. In many cases, books about similar subjects should be grouped together in the same location.

To help you decide which general area to look in, check out the L.C. Classification System Outline which appears below. If you have trouble finding your book on the shelf even if you know the call number, you should ask a librarian for help.
