Next click (do not press <enter>) in the Password box below. Type your password into the box and press <enter> or click <Log on to My Account>. (Tip: Your password is what you setup 6-14 characters.) You are now logged on, and you should see your name next to log out (upper right hand corner).
Click the Your name link in upper right hand corner. Click on checkouts and then on the book(s) you want renewed. Click on Renew my Materials. Follow any on-screen prompts to renew all or selected items. If the item cannot be renewed, return the item as soon as possible, or contact your local library.
