Over several decades of interviewing people and crafting their words into published works, Studs Terkel defined, expanded, and challenged the field of oral history. Terkel often described his methods as similar to those of a “prospector for gold” sifting through the statements of his subjects to create essays that reveal each person's “essence.” Drawing on his planning documents, interview transcripts, manuscripts and published texts, I trace Terkel's approach to oral history through two of his best-known works – Hard Times and “The Good War” – and through three stages: his planning and performance of interviews, his editing of the individual transcripts, and his construction of the completed text. I conclude by considering the implications of Terkel's unconventional approach to oral history and the ways in which his methodology may reflect his long history of involvement with progressive political movements. Terkel crafted his subject's narratives into texts I term “documentary memory”; he insisted that his works are subjective “memory books” but also employed a documentary rhetoric of objectivity. Terkel believed telling stories of the past to be a form of social action and he used his texts about the past to comment politically on his present – his “memory books” document earlier periods in American history relevant to the cultural moment in which he published.
