Lists of additions and changes to the Library of Congress Classification (LCC) schedules, from Weekly List 49 (December 6, 2006) to the present, are posted at https://classweb.org/approved/ as they are approved.
LCC approved lists from 2002-2021 may be accessed via a drop-down menu on the Classification and Shelflisting page.
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 Plus is the official and up-to-date version of the Library of Congress Classification. Classification Web Plus is available by subscription from the Cataloging Distribution Service.
