Steve,
I don't think it's so much find a control field (however, the closest match I
can use is ISBN or eISBN which has its issues) but also normalizing the data in
the fields so that matches are produced. It will no doubt take some time to
figure out.

Subject: Re: [CODE4LIB] De-dup MARC Ebook records
Michael Beccaria said:
Thanks for the replies. To clarify, I am working with 2 (or more in
the future) marc records outside of the ILS. I've tried using Marcedit
but my usage did vary...not much overlap with the control fields that
were available to me. I have a feeling they are a bit varied. I'm also
messing around with marcXimiL a little but I'm having trouble getting
it to output any records at all. I also was looking at the XC
aggregation module but I was having trouble getting that to work
properly as well and the listserv was unresponsive. It seemed like
good software but it required me to set up an OAI harvest source to
allow it to ingest the records and that...well...enough is enough... I
think I will probably need to write something, and at least that way I
know what it will be doing rather than plowing through software that
has little to no support. Please feel free to let me know of a particular
strategy you think might work best in this regard...
If you couldn't get adequate deduping from the control fields available in
MarcEdit deduping, what control fields do you think you need to dedup on? You
can actually specify any arbitrary field and subfield for deduping in MarcEdit.
