Our friends at Georgia State University have just launched a new resource, Works Progress Administration Maps of Atlanta. The site features over 950 maps including the 1940 Report of the Real Property, Land Use, and Low Income Housing Area Survey of metropolitan Atlanta, a 1936-1938 Atlanta Cadastral Survey, and a partially incomplete series of Fulton County land use maps from 1937-1940. You can also search the collection within DLG.
For more information, see their collection announcement.
