Pequannock residents can apply for a free library card. Residents are required to show proof that they live in town. Each card expires after three (3) years, but may be renewed with valid proof of address. Your library card can be used at the Pequannock Township Public Library, as well as any of the Morris County (MAIN) libraries. If you are in good standing, you can also receive an Open Borrowing sticker for your card, which allows you to borrow in participating Middlesex, Morris, Sussex, and Warren county libraries.
