> So wait, they're incentivizing people with overdue books to wait on average 6 months before returning them? In my public library system, at least, you can't check out new books when carrying more than $5 in fines. (I forget whether you have to return the books, or just pay the current balance.) Thus, it's not quite as simple an incentive system as that.
