Butler Library tries very hard to maintain good working relationships with other libraries! It is important to return books on time or we jeopardize our ability to obtain materials in the future. Borrowers who disregard due dates will have their ILLiad borrowing privileges blocked and will be unable to check out material until all overdue items are returned to the interlibrary loan office. In addition, the lending library may impose an overdue fine which is your responsibility to pay.
