Walker Library is currently in the process of moving from the Dewey Decimal System of classification to the Library of Congress (LC) system. During this process, we will be using both systems, with LC books and Dewey books on different floors. You can find a specific book's location and call number in the Library Catalog. If you would like to browse books by subject, the call number outlines for each system are below. We currently have books from all subjects in both systems; books acquired since December 2020 are classified in LC.
Books with LC call numbers are currently on the 2nd floor. Click each main heading for a more detailed call number breakdown.
