The day after the loan period expires, a reminder is sent by email.
6 days after the reminder has been sent, a fee-based first overdue notice is automatically issued for each item. A second overdue notice is sent another 6 days later, with additional overdue fees charged per item. See the fee schedule.
If the item is still not returned, a fee-based third overdue notice is issued for each item, and the library account is blocked.
