This atlas of Westchester County was created by the G. M. Hopkins Company between 1929 and 1931. It shows landmarks, geographical features, businesses, and some property ownership. The atlas is in four volumes ( Volume 1: southeastern Westchester; Volume 2: south central Westchester; Volume 3: southwestern Westchester and along the Hudson River to North Tarrytown; and Volume 4: northern Westchester from Mount Pleasant and North Castle on north). Each volume contains an index map at the start of the volume that details the area covered, and there is a street index and a subdivision index at the end of each volume. It has been indexed here by town name.
