Organization of the APA Library

The APA Library is organized according to a unique classification scheme. This scheme — the American Planning Association Library Classification Scheme — was created to meet the needs of today's practicing planners. The scheme focuses specifically on planning and provides a level of practical detail not found in other published systems such as Library of Congress or Dewey Decimal.

In the APA Library, books are shelved by class number while vertical file materials (plans, documents, reports) are filed by subject heading.
