Tracking the date/time that an item is due back to the library and returning it on time is your responsibility as a borrower. If any item you borrowed is lost, damaged, stolen or is overdue 90 days (for regular items) or 30 days (for short-term loan items), you will be charged the full replacement cost of each item, plus a $5 processing fee per item. For more information about the CSN Libraries billing process, view our Borrowing from CSN Libraries page.
