Ken Burns, creator of the definitive PBS documentary, "Baseball," refers to the National Archives as "the Nation's attic." For a program in July 2012, staff members of the National Archives at Atlanta decided to rummage through their archival "attic" to see what they could find related to the game of baseball. The result is a surprisingly eclectic mix of materials from federal agencies as diverse as NASA, the Bureau of Prisons, and the Forest Service, among several others.
