This book discusses the Austronesian diaspora and the ethnogeneses of people in Indonesian Archipelago, issues discussed in the International Symposium organized by the Indonesian Institute of Sciences (LIPI) in 2005 in Solo. As it concerns new findings and insights from different discipline perspectives and wrote by international scholars, this book should be very important to broaden our knowledge abour Austronesia and the Austronesian Speaking people. We hope that this book can motivate the development of Austronesian Study in Indonesia in the future.
