Introduction to Wright Library

An overview of how to find print and e-resources at Wright Library.

Library of Congress Classification System

The Wright Library uses the Library of Congress call number system to organize the collection by subject. Catalogers assign specific call numbers to books and journals. Call numbers are printed on the spine or front cover of every book and journal in the main collection. The bibliographic records in the online catalog (OPAC) provide the call number for items in the collection. The call number indicates both the general subject and the location of the item.

Anatomy of a call number:
