[Koha-devel] ISBN check

[Tomas Cohen Arazi]

I've been approached by one of our librarians asking for a way to
validate ISBNs inside koha. I've found

http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=906

but I need more infomration on:
1) The fields that need to be validated (MARC21 -> 020$a?, UNIMARC -> 010$a?)
2) The expected behaviour we want for this validation (I know 020$z
can be used for "invalid" or "canceled" ISBN, but aint no expert on
the subject): abort? warning? option to move ISBN to $z?.

I'm not sure also how is this related to the use of EAN instead of
ISBN by several publishers and if it has to be checked too (are they
mutually exclusive?). I didn't have time today to read the references
on this, and hence my question

Have a nice weekend.
