OK - I think I understand what check digits are for: Check digits are numbers that are based on a mathematical formula devised to help detect typical data entry errors... or something like that :^) When Using Check Digits with koha: Q0: What is the easiest way to allocate new koha library card numbers? Q1: Is there a Check Digit "standard" that is generally used for library card numbers? Q2: Is there a list of card numbers suitable for use with Koha? Q3: Is there a script that can be used with koha to generate a new number on the fly when creating new members Q4: Anything more that we need to know about using library card numbers with koha? Thanks, R.
