Weekly lists of additions and changes to the Library of Congress Classification (LCC) are posted on the Cataloging and Acquisitions Web site as they are approved. There are generally fifty-one weekly lists each year, with no list published during the final week of December.

The information in the weekly lists was formerly made available in a quarterly publication entitled LC Classification: Additions and Changes. That publication ceased with List 284 (October- December 2001).

The online product Classification Web is the official and up-to-date version of the Library of Congress Classification. Classification Web is available by subscription from the Cataloging Distribution Service.
