Archival Advisory Board: In 1919, the first session of the Indian Historical Record Commission passed a resolution requesting the Provincial Governments of Bengal, Bihar and Orissa to concentrate the old records of their districts in their Provincial Record Offices. In conformity with the pro-record ideals, the Regional Record Survey Committee for Bengal and Assam started working in 1946 at the end of the war with its first President, Sir J.N.Sarkar, Convenor, Dr. R.C.Majumdar and Secretary, Dr. N.K.Sinha.
In the year 2000 an Advisory Committee has been constituted for its academic and archival development with Prof. Benoy Bhusan Choudhury, as its Chairman.
