Provided another patron has not placed a hold on an item, patrons may renew items up to six times (two times for community users). Patrons can request renewals online through My Library Account, by calling the circulation desk at 419-772-2181, or in person at the Information Desk.



Fines vary based on type of material and accumulate until the item is returned. Students and community users are charged fines for all items. Faculty and staff are charged fines for OhioLINK items only.

After two overdue notices have been sent, items are assumed lost and patrons are billed for replacement costs and a processing fee. If the item is returned, the library will waive the replacement costs and processing fee, but patrons will still be responsible for payin the fine.
