ILL items typically, but not always, have a four-week loan period with a possibility to renew. Loan periods and approving renewals are determined by the library that owns the items.
ILL item due dates can be found on the item's paper book band, the emailed checkout receipt, from My Library Account (through PAWS or the library home page), or by logging in to Create or Track a Request on the Interlibrary Loan and Scan Request page.
