Library Username Don't like remembering your library barcode to log into your account? You can now set up your own username for logging into your library account. To do so, Log in with your barcode and PIN. Go to Modify Personal Information. Enter a username of your choice. It is as simple as that. Next time you want to log in, enter your personally selected username along with your PIN. If you forget your username, you can still log in with your library barcode. Once in My Account, you can go back to Modify Personal Information to view and/or change your username. NOTE: The system will not allow you to select a username that is already in use. See the FAQ for more detailed instructions.
