The Bible Society movement formally began in Shillong with the opening of a branch of the Calcutta Auxiliary in the year 1952. It became Assam Auxiliary in 1956 with its area of operations extending to the whole of Northeastern parts of India. In order to facilitate easier movement of Scriptures to the remote parts of the difficult terrain covered by the Auxiliary, a Scripture Distribution Center was opened in Guwahati in 1973. After the formal inauguration of the Aizawl Auxiliary in 1983 and Dimapur Auxiliary 1986, Shillong Auxiliary now caters to the Scripture needs of the states of Assam and Meghalaya.
