STEP 2.3 : FIELD UPDATES & DELETES

Ac2-1.png

Changes to the MARC21 communications format have made many fields obsolete. If one field has been replaced by another, the change is shown in the Tag Updates table in this section.

If the field has been made obsolete without being replaced, the field is simply deleted from the bibliographic record. Fields that are deleted as part of MARS 2.0 are listed in the Field Deletes List in this section.
