Yes -- in MarcEdit, you can select a field or what is called MARC21. This gives you somewhere in the neighborhood of 15 match points -- which you can decide to turn on or off. This is the best option available when you have data with poor control numbers or no control numbers. One thing to keep in mind, MarcEdit uses and scores specific fields when determining matches. What you want to do if you know that the isbns won't match is turn that off as a match point.

Subject: [MARCEDIT-L] merge records based on 100 and 245?
Hi,
I find myself cleaning up an old library catalog and standardizing it to LoC field entries. Of course MarcEdit has been incredibly useful retrieving LoC data by ISBN and merging records based on matching 020 fields.
Sometimes the 020 fields don't match, in which case I'm having a tough time merging the records. Sometimes this is attributable to typos in the ISBN. Fair enough. If the author or title is sufficiently unique, I can retrieve LoC records based on those values, but am them puzzled about how to use MarcEdit to automate the merge. Does MarcEdit support merges on anything other than 001/010/020/021/035? How do I use the Marc21 protocol at the bottom of the drop down on the merge utility?
Sometimes the 020 field doesn't match b/c the current catalog stores more than one ISBN in 020 and separates them with a semi-colon. What regular expression might I use to parse the first ISBN and store that in 020 for matching purposes (I'll temporarily record 020 in 021 and then restore after merging)?
More generally, when extracting records using the z39.50 client, is there a way to batch retrieve records based on matches of author AND title?
Thanks for your help.
Evan
