The present compiled work is based upon the research papers presented in the national seminar on ‘Ethnic Groups of North East India : Problems and Prospects’ organised by the department of anthropology, Dibrugarh University, Assam. The book covers a wide spectrum of issues, relating to ethnic groups, process of assimilation, acculturation and the development of ethnic consciousness among various tribes and communities of North East India. Renowned anthropologists and social scientists seek to make an objective analysis of the probable forces responsible for recent identity consciousness on the basis of first hand information from diverse ethnic groups. The academicians, policy makers and planners may find interest in the book and it may meet partially the long felt need of the researches on this line.
