The Edmondson Collection is disappointingly small. Occupying only 12 linear feet, the papers span the period of 1958-1964 and are largely related to his brief service as a senator. The majority of the materials consist of correspondence, but there are also speeches, press releases, travel records, clippings, campaign materials, and audio-visual items. The strength of the collection lies in its focus on Oklahoma state government, including Arkansas River projects and the repeal of prohibition in 1959.
