The department has a stock of commonly needed equipment items that can be checked out through the Libib system. The site has an updated list of everything the department has available to check out and you can place a hold on equipment on the site as well. If you don't check out the equipment beforehand, you'll need to do so using the kiosk when you come to the main office to pick up the item(s).
Everyone in the department should have an account linked to their @uchicago.edu (CNET) email address. If you are logging in for the first time, you'll need to click the "Need Password" button to set up your account.
