MARC recommendations from the MLA Encoding Standards Subcommittee's MARC Cataloging Inefficiency Task Group:
- For new bibliographic records, prefer recording medium of performance in field 382 over field 048. In existing records, generally do not update field 048 unless directed by local policy.
This recommendation is reflected in the MLA Best Practices in the RDA Toolkit.
