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").
- Note that a "Reference Code Element: Local Identifier" is required in the MARC encoding; this should be a unique identifier for a given record, within a 099 field. (We can alternatively support unique identifiers within the 001 field, as an alternative to the 099 field).
- 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.
