Welcome to the Mountainside Public Library

 Library to Resume Regular Opening Hours

The Mountainside Public Library is delighted to announce that we will resume normal hours of operation (summer schedule) as of Monday August 11th!  We would like to thank our patrons for their support and understanding during our many weeks of restricted scheduling.  We invite you all to drop by the library, see what’s new, and take advantage of the remaining weeks of the Summer DVD Special.  Please note that, although we are now able to resume normal hours, work on our HVAC replacement is not yet complete.  We hope there will be no further disruptions, but we do ask for your patience in the event of any unanticipated closures or restrictions.


The Mountainside Public Library is located on Constitution Plaza in Mountainside, New Jersey. The library features a large selection of books, periodicals, movies, music, audiobooks and reference resources. There are also public computer workstations, free wireless Internet access, a community meeting room, a children's center and regularly scheduled entertainment and educational events.
