As part of the move to the shared library system, library patrons who choose to get their library notices by text message need to be 'opted-in' to a new SMS service. Library authorities have begun opting their existing patrons into this service (May 2017).
Patrons who have been opted-in will get a confirmation text message from LibrariesIE saying ‘Thank you for opting in to the Libraries Ireland SMS Alerts service. To opt out login to your library account at http://bit.ly/library-acct’'.
If you believe you were opted in by mistake please contact your local library.
Patrons can choose to get their library notices by email instead of text, as explained here.
