Hi Olwen,
Actually the algorthim is a standard check-digit routine included with the barcodes that Horowhenua use. This used to be pretty standard to prevent miskeying. I have a spreadsheet somewhere that will calculate them if anyone wants it.
I'm reorganizing faculty library's collection and user information using koha. I need some information and manuals if possible about koha. Of course I could use this spreadsheet, how can I reach this document? best regards.
