Bibliographic fingerprint

Evergreen creates a fingerprint for each bib record, which can be found in the fingerprint column of the biblio.record_entry table. This fingerprint is used to group together different bib records in a Group Formats & Editions search in the public catalog.

The bibliographic fingerprint incorporates several subfields to distinguish between different items, including:

  • $n and $p from MARC title fields to better distinguish among records of the same series that may share the same title but have a different part.

The bibliographic fingerprint distinguishes among the fields contributing to the fingerprint. This helps the system distinguish between a record for the movie Blue Steel and another record for the book Blue written by Danielle Steel.
