The Lambertville Free Public library is generally open to the public free of charge for onsite use of library materials, library facilities, and the public access computers.

Membership -- which allows borrowing of books, audiobooks, and videos, as well as access to Interlibrary Loan services -- is free to all residents of Lambertville, and to city businesses.

Borrowing and Interlibrary Loan privileges are available to non-residents on an annual subscription basis. Subscriptions for non-resident borrowing are currently $30 per year.
