The University Loans Department lends books and periodicals to students and staff members of the University. Students must be "in good financial" standing in order to have a maximum of 3 books out on loan to them at any point in time. Staff members may have a maximum of 7 books out on loan. Both staff and student must first present a valid University identification card to the Loans Clerk.

The Loans Clerk examines ID cards to ensure their validity. The ID cards are also scanned for ID number. The Book Loan Database is automatically retrieved when the ID card is scanned. This database brings up information as to the number of books on loan to the staff or student.

For students the Loans Clerk logs into the Bursary Financial Information System (BFIS) to check their financial status. If the student owes money to the University, the book loan request is politely denied.

Providing that the student is in good financial standing and has not reached the maximum permissible number of loans, the Loans Clerk takes the book(s) and processes the request by scanning the book, then stamping the return date on it. In the case of staff the main concern is to check that they have not reached their quota of 7 books. Only when the Loans Clerk is satisfied that the staff member can borrow additional books, are the books taken from him, scanned and stamped. To complete the process, the ID card and book(s) are returned to the staff or the student.
