You may want to undertake an oral history project or track down oral histories that others have compiled by consulting the Oral History Index (Westport: Meckler, 1990) or the Directory of Oral History Collections (Phoenix: Oryx Press, 1988). Or you can simply search your library's catalog using the term oral history or combining oral history with a keyword. Also consider getting primary sources from a county or state historical society's collections or even from the archives of your own college or university. You may find yourself working with material no one else has analyzed before.
