[Koha] When importing records, question about matching rule

Hi David,


I don't know how to fix it, but I do know that you can't change an
ISBN-10 into an ISBN-13 just by adding 978 in front of it. The check
digit at the end of the ISBN changes as well. 


There are various converter programs on the web, which take into account
the check digit change as well. The easiest is at
http://www.isbn.org/converterpub.asp, but if you need the actual
calculations behind the conversion, you'll need to do some research.


Hope this helps at least a bit,

Subject: [Koha] When importing records, question about matching rule



When importing records, my matching rule works when ISBN matches
identically in both records .. so ... I need to modify my ISBN matching
rule so that it matches books that MAY have the prefix 978 in front of
the ISBN.


Does anyone know how to modify the matching rule so that 978MATCH and
MATCH will match?


My current rule is


Tag             020   (ISBN)

Subfield   a

Offset       3      ( I tried 3 so it would ignore the 978 but this did
not work) 

Length     0


Normalization rule :   blank


Happy Holidays everyone!!!
