Dupré Library organizes its books using the Library of Congress Classification Outline.

The system divides all knowledge into twenty-one basic classes, each identified by a single letter of the alphabet. Most of these alphabetical classes are further divided into more specific subclasses, identified by two-letter, or occasionally three-letter, combinations.

Listed below are the letters and titles of the main classes of the Library of Congress Classification. Click on any class to view an outline of its subclasses.
