📖 About Middlesex Public Library
Middlesex Public Library is the free public library of Middlesex Borough, a Somerset County community of roughly 14,000 residents sitting between the Raritan River and the Watchung Mountains. The library operates at 1300 Mountain Avenue in a building it shares with the borough's community room, keeping its doors open late Monday through Thursday — until 8 p.m. — so working families and students can visit after school and after work. A dedicated Children's Department runs storytimes and the award-winning Makerspace known as The Maker's Nest, where kids explore coding, building and STEM challenges. Adult patrons can use public computers, free Wi-Fi, printing and copying services, and a reader's advisory service staffed by reference librarians who curate personalised reading lists. The library belongs to the Stellar NJ cooperative, so a Middlesex card opens the shared catalog and unlocks NJ State Library digital databases through JerseyClicks, plus eBooks and audiobooks through Libby. Notary services are available Monday through Wednesday — call ahead to confirm availability.
