Library of Congress by Subject

Outline of the Library of Congress Classification System

The Western Libraries, like many academic libraries, uses the Library of Congress Classification system to assign call numbers. This system uses letters and numbers to sort books into subject areas, but each title does have its own unique call number. This outline of the Library of Congress Classification can be used to determine where titles in a general subject area may be found in our library. For more information about the Library of Congress Classification system, how to find materials in The Western Libraries, and other research help, please ask at the Research-Writing Studio on Haggard 2. A more detailed version of the LC Classification is available at the Library of Congress Webpage,
