Michel, Sarah asked if I would respond to your point...

Last December you said that you'd arrange to have the first GMA transfer
our 930 data to _both_ 866 tags _and_ copy set records. We really wanted
to explore the option of using copy sets for our GLIS summary holdings.
Unfortunately, the copy set records were never created during the GMA (we
were later told creating copy sets during a GMA is not possible) so we
were stuck with the 866 tags for our summary holdings.
It is becoming clearer to us that relying on the 866 may not be a good
idea, even for our closed holdings from GLIS. The drawbacks include: no
call number indexing, no location qualification, no transfers via mass
holdings update, no temporary transfers to reserves, no way to allow our
processing offices to edit locations or holdings without giving them
access to the whole MARC bib record, no reflection of holdings in GeoPac,
and the list goes on. We need to find a way to make summary holdings data,
including call number and location, accessible to the rest of the Advance
system.
What approaches would you suggest? I can think of two...
(1) Move 930 data to copy sets during the migration. Is this really
as impossible as it seems?
(2) Use 930's in the GMA to produce item records without barcodes
(852's if you like) that represent summary holdings. The 852 has
legitimate subfields for location, call number, and circulation
information, and we could put the summary holdings themselves into
the "accession" portion of the call number so that it displays to
the public. We would then, as an ongoing project, create real copy
sets for any record whose holdings we have to manipulate in any way.
Any warnings about these approaches?
How have other GMA sites dealt with their 930 migration? Do they not have
call numbers and/or not plan to include serials in searches qualified by
location?
Thanks for any insight you might offer!
