Hi, I'm struggling with how to make incoming records overlay existing records in the database using Vandelay within the client. I thought I had it, but it's not working for me again, at least not consistently.
The TCN in the records I'm testing is the OCLC number. I've tried importing edited bibs from our old system, which of course have the matching OCLC number, but although the Evergreen loader sees the collision, the overlay does not take place. I have a merge profile set up, but it doesn't seem to be used during the load. For instance, I have tag 029 listed in the Remove Specification, but when I loaded a new record (no collision involved) with 029s, they all stayed in the record. I have tags such as 590 and 690 in the Add Specification, but when I try overlaying a bib, the tag never gets added. I tried a record downloaded from OCLC, adding a 590. The record also had a 520 not found in the Evergreen record. That time, I had partial success: the 520 added to the bib, but the 590 did not. Do I have to define the 590 tag somewhere for Evergreen to accept it in a load? Also, is there a place where I can define record match points? We usually want only the OCLC number, but there are occasions when the 020 and 024 would be appropriate. Thanks, Mary Mary Llewellyn Database Manager Bibliomation, Inc.
