Defenders of threatened languages all over the world, from advocates of biodiversity to dedicated defenders of their own cultural authenticity, are often humbled by the dimensity of the task that they are faced with when the weak and the few seek to find a safe-harbour against the ravages of the strong and the many. This book provides both practical case studies and theoretical directions from all five continents and advances thereby the collective pursuit of "reversing language shift" for the greater benefit of cultural democracy everywhere.
