Ian- If you have the matching rule set up to match on the 010 subfield a using the LC-cardnumber index, then the matching should happen if 1. your authority records are indexed 2. you have 010$a in your existing records AND in the incoming records (and matches do exist). (I'm assuming here that you've also specified the incoming file is an authority file, not a bibliographic file. ) I'm not sure that using a 020 will assist you in matching as that is a bibliographic tag, not an authority tag. And I do not believe the 020 is indexed for authority records. A tag must be indexed in order to be used as a match point. When troubleshooting, I generally find a record I know should match and then look at the 010$a in the incoming file and existing record to see if there is anything that would potentially cause the match to fail. -Joy On Tue, Dec 22, 2015 at 9:22 AM, Christopher Davis <cgdavis@uintah.utah.gov> wrote:
Ian,
Off the top of my head, I thought that you might want to tried adding MARC authority field 020 (ISBN) as a match point to your matching point rule? Not every MARC authority record will have a LCCN (although most do).
Good luck and Merry Christmas,

Hi.
We are trying to stage some authority records to match existing authority records to overlay them. We have used the matching for bibliographic records successfully before but are having difficulty with matching authority records. The version of Koha is 3.20.01.000 and we are MARC21 using dom indexing and icu chains.
Before getting into the details, can I ask if anyone has any experience of matching authorities (staging and managing) with any success?
We are trying to match on the 010$a and looking at the matching rules documentation in:
http://manual.koha-community.org/3.20/en/catadmin.html#recordmatchingrules
Thanks in advance.
