What we store. (Score 1)

I work in a college Library. Yes our system tracks what you CURRENTLY have out, that's obviously needed. It does not store a history of what you've had once those books are returned. However, one thing it does store is the last patron to have a book. This is needed, for example, in case a book comes back damaged and it's not caught on check-in. It's then possible to create a list of books where that person is the last patron to have them, but depending on turn over, this list could be quite short.
