I'm migrating a small elementary school library from Follett to Koha. All has gone well until now. Our problem is a mismatch between the barcodes as read by the scanner which give readings like T 3210 and our biblios in Koha which have the codes like T0003210. At first I thought it was the Follett 3800 scanner that was dropping the zeros, but a new generic scanner reads the same way. So what is the easiest fix? I can imagine four but none sound easy: 1) Reprogramming the scanner -- seems possible but the manual is written for a barcode expert (so many different formats and sub formats) -- how do I express the kind of change I want to make in the language of scanner firmware? 2) Batch changing the biblios from within Koha -- it seems to support batch work but you have to list the items. I can't work out how to make it change every single record. 3) Batch changing via the MySQL database -- I don't know SQL, so there is a serious learning curve 4) Going back to the MARC records, massing the barcode field there and then reimporting -- I don't know how easy that would be in MarcEdit and I am loathe to go that many steps backwards. Could anyone provide some wisdom to help?
