As of today, you’ll need both your library card number AND your MCLS library password when signing in to or verifying your account in Libby/OverDrive.
Already using Libby? You may not notice a change right away, but you’ll need your password the next time Libby asks you to verify your library card.
Don’t know your password? No problem! Your MCLS password is the last name on your library account.
👉 We recommend checking your library account now to make sure your information is up to date, so you can keep enjoying your ebooks and audiobooks without interruption.
