[Koha] Library card numbers, branch entry

[Bigwood, David]

The is a kind of de facto standard for public library patron numbers.

The 1st number is a 2 (3 is used for collection materials)
The next 4 numbers are the library number. There were once assigned by
Bowker (if I remember right) but they stopped that years ago.
The next 8 numbers are the patron number.
The last digit is the check digit.

So the number 2999900000001X means this is a patron (2) in the library whose
code is 9999 and is the 1st patron. The check digit system does not use X
like they do in ISSN and ISBN, I only used it as a place holder.

But, then there are many libraries who do not use this system, so any system
needs to be able to handle other formats. Many school libraries seem to use
the student ID number for instance.

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.
