Photogrammar – WPA photos
Yale University and the National Endowment for the Humanities have indexed the 170,000 photos created by the US Farm Security Administration and the Office of War Information. All photos were created from 1935 through 1945. Photogrammar organizes the photos so they are searchable via map location, photographer, classification tags (medicine and health for instance), and eventually by treemap, metadata dashboard and colorspace.
