The following documents the changes contained in the second update to the 2000 edition of the MARC 21 Format for Classification Data.  Update No. 2 (October 2001) includes changes resulting from proposals which were considered by the ALA ALCTS/LITA/RUSA Machine-Readable Bibliographic Information Committee (MARBI) at its meetings in 2001 and by the Canadian Committee on MARC (CCM) at its meetings in 2001.


There are no substantive changes to record, however, several examples have been updated and data element descriptions have been revised.
