Interlibrary loan item due dates can vary, as each library determines the due date for their own item. The due date will be included in your pick-up notification email, and written on the item label.
Renewals are not guaranteed for ILL items - if you are interested in renewing an ILL item, please contact clark-m@mssu.edu before the item is due so that a request for renewal can be submitted to the lending library. The earlier, the better! The lending library may or may not agree to renew the item, in which case the item will need to be returned by or before the original due date.
Due dates are not assigned to ILL copy requests, such as chapters or articles, which are photocopies that users may keep.
