Since Allan Nevins inaugurated the first systematic program of oral history in the United States at Columbia University in 1948, a large number of such projects have been conducted by universities, associations and corporations. Part I of this paper presents the question of whether oral history is credible historical evidence. The rules of evaluating historical evidence are presented, as well as the methodology of collecting, editing, and preserving oral history testimonies and recollections. The oral history methodology is described, and it is concluded that oral history must be judged by the same standards of criticism which historians would apply to any document. Part II discusses the current oral history project at Brigham Young University and the relevant need for an expanded project. A proposal is outlined for such an expanded project, based on utilizing graduate students in history as interviewers and processors, thereby drastically cutting the cost of this otherwise expensive procedure. The appendixes of this document include a select bibliography on oral history and the processing and agreement forms needed for oral history interviews. (Author/SL)
