List of MARC 21 fields to consider when exporting
Hamnet records originate from a variety of sources, and were created and updated over a long period of time. Some fields and subfields now considered best practice (or even mandatory) will be lacking.
Fields and subfields to add/modify
- 040$b "eng" (language of cataloging)
- 041$a check for records where $a (now repeatable) contains more than one language code
- 049 delete (locally defined by OCLC, contains OCLC symbol of holding library)
- 1XX$0 check records that also contain 240$a in case link goes to Authority record for Author/Title combination instead of Author.
- 852$a "Folger Shakespeare Library" (or "DFo" if MARC code is preferable in context)
Fields and subfields to explain
- 035$a "OCoLC" number is for identification purposes only; Hamnet is the Folger's database of record, so additions, enhancements, and corrections (if they do not affect WorldCat searching) are only made in Hamnet.
- 245$h (GMD) is retained in Folger records, for display and searching puposes.
