Prepare MARC21 Files

  • For recommendations on encoding MARC collection guides, see our UC Bibliographic Standards for Cooperative, Vendor, and Campus Backlog Cataloging [PDF] (Appendix B, "Collection Level Records").
  • Files must be in the MARC 21 format (i.e., not MARCXML). Note that a single file may constitute an individual MARC record, or may constitute multiple MARC records.
  • We recommend naming files using lowercase letters and numbers, underscores, or dashes; do not include spaces. Use periods for the file extension only.
  • Use .mrc or .marc as a file name extension. Do not include punctuation at the end of the file name.

Submit MARC21 Files
