To learn about Harry Caudill, reporters for the Lexington Herald-Leader spent months interviewing many people who knew him personally, including his widow, or were familiar with the historical impact of his writing. They read Caudill's books and his most influential magazine and newspaper essays.
Reporters also relied heavily on the Anne and Harry M. Caudill Collection at the University of Kentucky Special Collections Library. The collection includes more than 100 boxes of original manuscripts, notes, personal and professional correspondence, photographs, speeches, testimony, reports and other documents produced or collected by the Caudills over 40 years. Unless otherwise noted, documents that are quoted in this story may be found in the collection. The Caudills donated their papers to UK after Harry Caudill largely retired from public life in the mid-1980s.
Another key source of information was the Harry M. Caudill Oral History Project in the Louie B. Nunn Center for Oral History at UK's Special Collections Library. This contains 18 taped interviews with Caudill's friends and associates, conducted nearly a decade after his 1990 death.
