Auto Renewal is a feature which renews eligible items that are checked out to patrons in good standing, in an automated process, using Courtesy Notices. Two days before the item is due, the patron will receive an email notice to inform them that their item has been renewed and will now be due at a later date. If an item cannot be renewed, a courtesy notice will still be sent with a reminder that the item is due. Only items that are already eligible for renewal can be automatically renewed.
