The main branch of the Woodbridge Library has come a long way since 1877, when the Barron Library — now the Barron Arts Center — was constructed to serve the voracious reading appetite of Woodbridge residents. The Main Library, built in 1974, is a unique modern structure with a long, two-way ramp ending at the library door. The lower level houses a children's section and a variety of meeting rooms for township groups. The main level of the library has wireless Internet access throughout, an extensive periodical and reference section, and a large book collection.
The Main Library is the centerpiece of the township's network of four municipal libraries — Fords, Inman and Iselin — plus the independent Sewaren Library. The library boasts a friends group that holds an annual sale in April to help with library funding. The library director is Christine Murchio.
