The collection includes photographs including World War II era photos of his platoon, contemporary photographs of Peleliu and Okinawa, and photographs of Veteran's groups. It also contains articles by Sledge and other authors concerning World War II in the Pacific, clippings relating to the 50th Anniversary of World War II, correspondence (including wartime correspondence) and artifacts.
