When doing the merge process, I actually recommend letting MarcEdit use the
MARC21 option. This does the control number matching by default (and more
advanced control number matching) and works on multiple, repeating fields.
However, for records like these, where match points exist in different
fields, it also uses the entire records themselves to create matches. You
would want to test the accuracy, but it's likely as good, or better, than
any matching OCLC does within WorldCat to merge duplicate records.

Subject: [MARCEDIT-L] Replacing "missing" LC call numbers
We are currently a DDC library and our library catalog contains myriads of
records that had the LC call numbers stripped from our records. We would
like to embark upon a project whereby we reinsert these call numbers back
into the files.
We currently do not use OCLC's WorldShare Metadata Collection Manager,
though plans are being made to begin such in the future. We have also added
a great deal of local enhancement to our records, which may or may not have
been updated to the OCLC master record (which creates some concern as we
look to the future rollout of the bibliographic update service).
So, I've laid out a process whereby we can identify and download OCLC
records by number, as well as those in our catalog without an 050 or 090.
The goal is to merge two files using a matchpoint. The difficulty is that
sometimes the matchpoint will be the 035, but if OCLC has merged records
since our acquiring and cataloging a resource, the matchpoint would be an
035 in our local record and an 019 in the OCLC record.
I've got the 035 to 035 process down, but any suggestions on how to account
for the matchpoint residing in different fields?
Is the solution to copy the 019 to multiple 035s? If so, how can a single
019 be split into multiple 035s? Also, during the merge process MARCEdit can
handle repeating fields, but it wants to know which field is to be the
matchpoint.
Any recommendations would be welcome.
