Every library I ever used had overdue fines per day for late returns. They would have to keep track of when the book was actually returned in order to calculate that.
I don't believe you've actually demonstrated any standard. You gave a single example and assumed that it was a standard.
What is your evidence that the actual return dates in this specific case were not available?

No, they did not need the actual return date (unless the book became overdue). And in that case, all they needed was how many days it was late (after the due/return date). And they had the due/return date information by using the standard system already described. The elapsed days between the return/due date and when the book(s) were returned was multiplied by the per day rate. Why do you believe they would have gone to the trouble to track unnecessary information?
I don't believe you've actually demonstrated any standard. You gave a single example and assumed that it was a standard.My contemporaries and I grew up using the manual system and
remember how it worked. It was THE standard system used before computerization, not just a single example as you imply. If you believe there was another system (that included the actual return dates) in use back then in the New Orleans Library System, then where is
your evidence of such a system? Otherwise,
you are the one assuming something that was not at all common.
What is your evidence that the actual return dates in this specific case were not available?The standard manual library system did not have that information. The SS report list shows every "return date" as exactly two-weeks from the "date would have been checked out," which is evidence and consistent with the case that the New Orleans Library System used that type of system. What is
your evidence that the New Orleans Library System used a system that
did have that information?
