Researchers interested in Swift's activities as an official of the Wisconsin Conservation Department will want to consult the extensive files of that agency held by the State Archives at the Historical Society. The Historical Society Archives also holds a lengthy, transcribed oral history interview with Swift (Tapes 346A and 381A) conducted in 1964, and in the Library is a copy of his Glory Trail: The Great American Migration and Its Impact on Natural Resources. The Walter Scott Papers, also held by the Archives, include a few additional Swift speeches and a few post-retirement letters.
