Library of Congress Classification System

The Library of Congress Classification system organizes materials in libraries according to branches of knowledge. Originally devised for the U.S. Library of Congress, it is widely used by research and academic libraries to organize their collections.

In the Alvin Sherman Library, the Library of Congress System is used for most of the collections, including most circulating books, reference collection, etc. The children's and young adult collections in the Alvin Sherman Library use the Dewey Decimal Classification System, while sound recordings (compact discs and cassettes) are classified by ANSCR, the Alpha-Numeric System for Collections of Recordings.
