I.N. Phelps-Stokes’s six volume The Iconography of Manhattan Island, 1498-1909 is an invaluable text that includes information not just about Manhattan, but about Long Island and Brooklyn as well.

Eugene Armbruster’s The Eastern District is an excellent resource for the history of Bushwick, Williamsburg, and Greenpoint, and especially helpful in understanding street name changes.
