P.C. Joshi (1907-1980), a legendary figure in the history of Communism, together with the assistance of K. Damodaran (1912-1976), a veteran leader of Communist Movement in India, colleted these materials over a long period. A compilation of source materials, coming from the pen of such a man, who was the General Secretary of the CPI (1936-1948) in the most crucial period in the history of the CPI, therefore, deserves special attention.
