Cards also are only valid for 5 years then they expire. I had an issue like that too in the past not sure of why it was not working until I was informed that the card may have expired after some time also if it remains inactive after a few years of not being used. If either of these happen you just need to renew your card and is simple to do.
Hi Joy, If the Libby app isn't recognizing your library card number the quickest thing to do is call the Reference Desk at 781-721-7171 ext.320. Staff can verify that your card is active and reach out to the folks at Libby if we can't remove the issue.
