Auto-renewal is a service for the Library that automatically renews physical materials that have available copies on the shelf. Items will automatically be renewed two days before their due date. The new due date will be extended from the original due date, so you will still enjoy a full loan period after each automatic renewal.
Please see our FAQ, "Why am I unable to renew the item I have borrowed?" for exceptions and restrictions on auto-renewal. Please note that eBooks and eAudiobooks do not renew automatically.
