Check out your books at the circulation desk. You also request and pick up items from Interlibrary Loan here. Your Saint Louis University ID serves as your library card as well as your ticket into Pius Library. Study rooms and typing rooms are available with a valid SLU ID. Lockers can be rented for $2.00 per academic year. Two other service units, Interlibrary Loan and the Reserve Room are also part of the Circulation Department.
