Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive.

July 1942. Melrose Park, Illinois. "Production of aircraft engines. Buick plant. Foreman F.I. Bowman shows Marietta Morgan how to operate this bomb-test machine used to test reconditioned spark plugs. A young Negro girl, Marietta had been a clerk in a meat market. Her lack of industrial experience, however, has been no handicap for her present war job in a large Midwest airplane plant. She's rapidly becoming a skilled and efficient machine operator." Medium format safety negative by Ann Rosener for the Office of War Information. View full size.
