The National Archives of India (NAI), which is responsible for preserving the records of the government of India and its organizations, does not have records of significant events such as the 1962, 1965, and 1971 wars and the green revolution.
This is because a number of government ministries and departments have not shared their records with the NAI since independence. The NAI has records from only 64 of the 151 total ministries and departments in the country. The director general of the NAI emphasized the importance of records management in government and expressed concern that India may be losing a significant portion of its history due to the lack of record sharing. He also pointed out that unauthorized destruction of records is punishable by imprisonment. The NAI is responsible for appraising and reviewing records to identify those that should be transferred to its care.
