The maps and atlases in the Trentoniana Collection range from hand drawn to bound plate books. Some of the maps were found inside city directories, which were the telephone books of their day. A list of hard copy maps and atlases for use in the Trentoniana room can be found here.
Over 100 maps have been digitized through a grant from the New Jersey Historical Commission, a Division of the New Jersey Department of State. The digital map collection is hosted online by the New Jersey Digital Highway and can be browsed via the portal below.
