[OPEN-ILS-GENERAL] Need help with edit/merge overlay profile for batch importing

[Mary Llewellyn]

Hi all,

One of our libraries has informed us they are getting their own subscription
to Overdrive, departing from our group consortial subscription. Since they
will have a unique URL for their patrons, and since many of their titles
will probably be the same as ours, I need to be able to load their MARC
records, have them match on the existing bibs, and add their 856 to the
existing record. The result will be at least 2 856 tags, one with their URL
and one with the Bibliomation URL. We will be using subfield 9 with their
system short name to allow their link to show only in their catalog, while
our 856 will contain a string of subfields 9 for the other subscribing
libraries in our group subscription.

However, I can't seem to work out the right settings for the Edit/Merge
Overlay Profile in the Evergreen client. The obvious one to me would be the
"Add" line. I entered "856" on that line and saved the profile, but when I
use it, the records will not merge or overlay. They will not import at all.
My import settings were "Merge on single match" and I specified the merge
profile I had created. 

Thinking outside the box, I tried entering 856 in both the "Preserve" and
"Add" lines. This time the records imported, but did not add the extra 856. 

I know I don't want to use "Replace." That will remove our 856  and put the
single library's in.

Is there anyone out there that can help me work this out?

Thanks,

Mary
