Deleting MARC Tags from Incoming Bibs
Use the following Cataloging Administration settings to delete specific MARC tags from bibliographic records that are being saved to the database:
- Bibliographic Tags to Retain/Delete - Use this policy table to specify tags to be deleted automatically if the user selects the following options in an import profile: Delete MARC Tags on incoming record and Profile-defined deletion tags. The tags specified for deletion in the policy table are also deleted from records when they are found via a Z39.50 search of a remote database and saved to the Polaris database if the Delete MARC tags when saving Z39.50 records to local database profile is set to Yes.
Note:
Import profiles can be set to delete the system-defined tags or to delete tags defined in the profile.
- Delete MARC tags when saving Z39.50 records to local database - When this profile is set to Yes for the system, library, or branch level, the tags specified for deletion in the Bibliographic Tags to Retain/Delete policy table are deleted automatically when records found via a Z39.50 search of a remote database are saved to the Polaris database.
The following tags cannot be selected for deletion in either the Bibliographic Tags to Retain/Delete policy table or in the import profile:
- LDR
- 001
- 003
- 005
- 008
In addition, the following tags are used in duplicate detection and should not be deleted.
- 010$a
- 020$a
- 022$a
- 024$a
- 028$a
- 035$a
- 037$a
- 1xx$a
- 245$a
- 246$a
- 247$a
- 260$c
Tags are never automatically deleted from bibliographic records when:
- the new bibliographic record is created manually by entering tags in the MARC 21 view of the Bibliographic Record workform;
- a new bibliographic record found during a Z39.50 search is saved as a Bibliographic Record template;
- or, a new bibliographic record is overlaid by the database record during importing.
