[Koha] Multiple record matching rules

[Christopher Davis]

Paul,

Thank you for your advice on trying the record matching rules. My
institution actually already employs the record matching rules to match
incoming MARC records on ISBN, but after reading the help file on these
rules, I could not discover how to sequence multiple match points. When I
looked at the rules again, I realized that the way to do what I wanted to
do was staring me in the face. What I needed to use was the "Add match
point" link found on the first match point. SORRY FOR THE FALSE ALARM.
