Step 2.4 Question
Indicate if you would like the Tag Updates & Field Deletes processing performed. For additional field deletions, or to modify selected changes, please fill out the online profile part “With these modifications” including any changes desired.
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 If one field has been replaced by another, the change is shown in the Tag Updates table in this section.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 the MARS 2.0 Update processing are listed in the Field Deletes table in this section.
