For how long are Interlibrary Loan materials renewed?

As renewal periods are set by the lending library and not by PSU, there is no set period of time for a renewal. When a renewal request is submitted, the due date is automatically extended (generally seven days from the original due date). This is done to allow the lending library time to respond. Interlibrary Loan will send an email detailing the status of the renewal once the lending library has responded.
