Documents from Rockefeller's two terms as governor from January 1967 to January 1971 can be found in Record Group III. His governor's papers include letters from constituents and Republican supporters, files for state and county boards and commissions, executive files, legislative materials, files on Arkansas counties, governor's proclamations, and items concerning regional tours. This record group also includes correspondence and other papers from his unsuccessful bids for office in 1964 and 1970.
The files related to Rockefeller's reform of the Arkansas prison system and his controversial communication of sentences for death row inmates offer an interesting but largely unexplored area of research.
