The following change list was included as Appendix G of MARC 21 Format for Bibliographic Data, 1999 Edition, published in the February 1999 Erratum.

This edition of the MARC 21 Format for Bibliographic Data supersedes the March 1994 base text and updates No. 1 (March 1995) through No. 3 (July 1997) to the USMARC Format for Bibliographic Data as well as the September 1993 base text and updates No. 1 (October 1994) through No. 6 (January 1998) to the Canadian MARC Communication Format for Bibliographic Data.  It includes changes resulting from proposals which were considered by the ALA ALCTS/LITA/RASD Machine-Readable Bibliographic Information Committee (MARBI) at its meetings from 1998 through February 1999 and by the Canadian Committee on MARC (CCM) at its meetings from 1998 through February 1999.

The following changes were not included in Appendix G:

The requirement to use the fill character ( | ) where no attempt has been made to code a position has been emphasized by its explicit addition to the code lists for all defined 006, 007, and 008 character positions, except 007/00 and 008/00-05 where it is not permitted.  (The fill character code is defined as "No attempt to code.")  This is not a change in the requirement, but rather an emphasis of it.

Subfield $8 (Field link and sequence number) has been added to all variable data fields, except 018, 042, and 066.
