Log in to your library account with your library card number and PIN. (if you don't have a PIN yet, here is how to get one.)
Click the 'My Reading History' button. If you have not yet created a Reading History, you will see the message 'No reading history available'. Click the 'Opt In' button to start collecting your Reading History. Once you 'Opt In', the library catalog starts recording a list of the items you check out from that time forward.
Items you have already checked out at the time of opting in, like items you have read in the past, will not be on the list. After opting in to Reading History, anything you check out will be added to the list, and you can see it whenever you enter the Reading History display.
