This section is provided for the lists of format changes that accompany each update to the MARC 21 Format for Classification Data. It can also be found in Appendix E of the MARC 21 Format for Classification Data.

This edition of the MARC 21 Format for Classification Data supersedes the December 1990 base text and update No. 1 (July 1995) to the USMARC Format for Classification Data as well as the March 1992 base text to the Canadian MARC Communication Format: Classification Data. It includes changes resulting from proposals which were considered by the ALA ALCTS/LITA/RASD Machine­Readable Bibliographic Information Committee (MARBI) at its meetings from 1998 through January 2000 and by the Canadian Committee on MARC (CCM) at its meetings from 1998 through January 2000.
