As a condition ultimately granting release of his 1990 interview, Fred Burelbach asked for three pages to be removed. The interview transcript, minus these three pages, was released in accordance with his wishes. Reesearchers may read both the typed transcript (Series 2) and the corrected version (Series 4) and listen to tape 2 (Series 1). The three corrected pages and tape 1 of the interview are permanently sealed.
