In the interest of making the checkout process quick and convenient for our patrons, the Central Library has a number of self-checkout machines available on the first, third, and fourth floors. With just your library card and PIN, you can check out library materials on your own. If you forget your library card, you can enter your card number by hand. Self-checkout machines can also be used to view and renew your currently checked out items, and to pay your library fines. Reference materials cannot be checked out at these machines, as they do not circulate.
