Hello, all! My library will soon upload a lot of records (bibliographic with item records) into its Koha ILS. We have observed through experimentation that if the check digit of a barcode does not compute according to one of the standard modular arithmetic formulas, the item record is rejected. Not just the barcode, rather the entire item record. Mind you, the bibliographic record makes it in, but the item record with the miscalculated check digit does not. If the barcode is not in the item data but the rest of the item data are, the item record will make it into the ILS. Is there a way to suspend the check-digit calculation during the uploading process, e.g., a preference/option/setting called something like BarcodeDigitCheck? Mind you, my staff and I can type in the barcodes and we may use this for an inventory check -- pardon the pun. Thanks for your help, all. -- -- Charles.
