Contact the library and we will work with you. You are responsible to pay the replacement fee of a lost item, including Prospector and Mobius library items. The standard replacement fee for a lost or damaged book is $50; the standard replacement fee for DVDs and CDs is $30. If a lost ("billed") book is returned the maximum fine charged is $10 (certainly less than the replacement fee). Fines and fees can be paid with cash, check or by purchasing an Amazon eGift card for the Library in the fine or fee amount.
