Library of Congress Classification System
USU Libraries use the Library of Congress classification system (LCC) to organize our collections by call number. Academic and research libraries use this system instead of the Dewey decimal system, as is common in public and K-12 education institutions. The Library of Congress system is divided into classes and subclasses by subject, which are used to create an alpha-numeric call number for cataloging library materials. To browse LCC classes, see this outline of Library of Congress.
