The authors were furnished numerous interviews with Edgar Daniel Nixon by various journalists, historians, and scholars. Bill Edwards interviewed Nixon in the 1970s. Tom Gardner and his then-wife, Jennifer Johnson, interviewed him extensively during July 1985. Mike Williams also interviewed Nixon in the mid-1980s. Both Gardner and Williams were reporters for the Montgomery Advertiser at the time of their interviews. Other interviews with Nixon, conducted by television journalist Norman Lumpkin, were made available to the authors by the Alabama Center for Higher Education, Statewide Oral History Project, Tuskegee Institute. Although we did not use direct quotes from any of these, they were valuable in that they allowed the authors to compare their own notes with others in order to ensure accuracy of dates, facts, and other items. Wayne Greenhaw interviewed Nixon many times from the spring of 1967 until shortly before Nixon's death on February 25, 1987.
Papers and letters of E. D. Nixon were made available by the Levi Watkins Library at Alabama State University.
