Thank you for visiting the Mountainside Library website.
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."

If you have any comments, questions or suggestions, please let me know. You can send an e-mail to or call 908-233-0115.

See you at the Library,

Kathryn Brown
