These charges are processed through the University's Accounts Receivable office onto student accounts.
Students receive a single bill that includes tuition as well as all other university charges.
This offers several benefits. First, the library doesn't collect large amounts of money over the counter. Second, it eliminates the need to have an accounting office within the library. It is also an incentive for students to return books in the lost category. The library has been using this process for over 15 years.
