Copley Library has 30 laptop computers for check out—18 Macs and 12 Dell PCs. The laptops can be checked out by USD students for a 3 hour period. The machines are loaded with a comprehensive selection of software. If used within the library they can print wirelessly to the 3 printers using Campus Cash for payment. The machines may be used outside the library, but not off campus. To check out a laptop, the student must have a valid USD ID card and sign a financial liability agreement.
