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.

We have a lot to offer and hope you’ll take time to explore our site. In addition to our online catalog and array of electronic databases, we have a terrific photo gallery that chronicles the last several years of library history. And many people find our schedule of programs and activities a real convenience.

Libraries are exciting places and, in many ways, have become bustling community centers. Seeing us on the Web gives only part of the picture; be sure to visit us in person to really see why we say “the public library is the heart of the community.”
