University libraries uses the Library of Congress (LC) classification system. This system organizes books and other library materials by subject, to make it easier for you to browse the shelves for materials on a specific topic. Library of Congress call numbers always begin with letters of the alphabet. This system is organized into 21 main classes which are designated by letters of the alphabet.

Each book is given a unique call number chosen according to the LC system, and the books are arranged on the shelves in order by that call number. The partial outline below may be useful for browsing the shelves:
