Dear Colleagues,
I know that Koha can match the ISBNs of imported MARC records with the
ISBNs of existing records, but is there a way to configure a record
matching rule to try to match more than one match point at a time (for
example try to match ISBN, then try ISSN, then try LCCN, then try OCLC
number, then try standard number, then try publisher number)?
Have you tried ==> Administration ==> Record Matching Rules?
We have defined seven rules, mostly the obvious ones e.g. ISBN, ISSN (we
don't use OCLC -- can't afford them -- and I'm not sure what you call
'standard number'), author, title, publisher, pub date and manufacture
date) and then refined them with dates from 008 etc. It takes a little
time to fine tune the flexibility. It gets a very few false positives
"Are you sure this isn't a duplicate?" but otherwise appears to be
extremely reliable.
We dropped LCCN matching -- many of our older books (we're basically an
international archival library) don't have one, and the regex
"treatment" of leading spaces, hyphens and suffixes became CPU
cycle-heavy for minimum joy.
YMMV and HTH. Best -- P.
