The series of Man and Environment in Northeast India is aimed to give an insight into the art and culture of Northeast India, which is long been considered as a little known territory of the World. After the successful publication of Volumes I, II and III in 1993, 2002 and 2008 respectively, the Volume IV will highlight the enormously rich cultural resources of Northeast India which was formerly the undivided Assam. This Volume will bring this region and its cultural heritage to the knowledge of academicians in India and abroad. It is the forth production in the series of a project that Dilip K. Medhi initiated and conceived in the eighties of last Century. The author is aware of the fact that the Assam Region is one of the largely undiscovered territories of the world. Medhi shall bring out more Volumes in this series in the coming years in order to make Anthropology and Archaeology together with other relevant subjects belonging to Social Sciences known to the academic world; he shall further bring out more Volumes on the scientific knowledge of the region.
