Word of the day: Due Date

You’ve been arrested for two overdue books,
so what’s up with the big smile you big goof ball?

1. The date on which materials must be returned to the library.¹
2. The date the patron insists they never saw on the due date slip.
3. The date the patron starts reading the library book
4. The date that falls about a week before they ask for a renewal.
