A new feature of the computer system is a "pre-overdue" notice delivered to your email.  If you have signed up for email notification of reserve books or overdue notices, you will now also receive a pre-notification three days before the items are due. This will keep you from having overdue notices, or alert you to renew an item if renewal is possible.  This courtesy notice will not be available on the dvds or videos that have a three day loan period.
