The problem here is assuming that everything must be computerized... for no good reason other than everything must be computerized. When I was six, the teacher pulling a card from the pocket in the book, having me print my name, stamping the card and the book with with the due date, and then filing the card worked just fine. I'm no luddite or technophobe by any stretch, but sometimes electronic/automated systems are solutions in search of a problem.
Inventory, late-return spreadsheets, a central database over an entire district, tracking moving children and their withdrawn books. And that’s just from the top of my head. Computerizing the library is a huge, huge positive step forward.
My sister opened a computer store in Hawaii. She sells C shells down by the seashore.
