Paul, Thanks Nicole. Good background (shame that our budget doesn't permit full
membership of WorldCat) but I'm still looking for the technical background for ease of cataloguing. Am I correct in summarizing:
- the "RLIN" is not searchable, per se, and its appearance in the GUI serves no useful purpose to cataloguers?
That is not correct, no. You can search it using the prefix an: - therefore, all frameworks can "hide" (but not delete) all
subfields referring to RLIN?
It would be best not to delete subfield $9 from fields that are authority controlled. Other subfields referring to RLIN can be deleted at will. Assuming its use for indexing authorities, it appears to be just as
important as biblio and item numbers, but where and under what name is this data stored in MySQL?
It is stored in the MARC in subfield $9. The relationship is not represented in SQL. Regards, Jared -- Jared Camins-Esakov Bibliographer, C & P Bibliography Services, LLC (phone) +1 (917) 727-3445 (e-mail) jcamins@cpbibliography.com (web) http://www.cpbibliography.com/
