Indo-Aryan Controversy [PDF ebook] 
Evidence and Inference in Indian History

For the first time in a single volume, this book presents the various arguments in the Indo-Aryan controversy. It also provides a template for the basic issues addressing four major areas: archaeological research, linguistic issues, the interpretation of Vedic texts in their historical contexts, and ideological roots. The volume ends with a plea for a return to civility in the debates which have become increasingly, and unproductively, politicized, and suggests a program of research and inquiry upon which scholars from all sides of the debate might embark.
