Stay up-to-date on all your Library account activity! Sign up for this free service and receive updates on items on hold for you that are ready to be picked up, overdue notices, and courtesy notices for items that will be due soon. You can even send a text message to renew your items.

Sign up by texting the message SIGNUP to See How do I send a text message to an email address (below) if you need help sending a text message. The service will contact you back with further instructions to send your library card and PIN numbers. It’s that easy!

By default, you will be signed up to receive messages when a hold is ready for pickup, two days before you have items due, and when your items are overdue. If you’re happy with these settings, you’re done! If you want to turn off one of these settings or use advanced features, keep reading.

NOTE: At this time, notifications for items requested from other libraries through the LINK+ system are not included in ShoutBomb text messaging. You will still need to check your library record online for these items or use email notification.
