This revised edition includes updated bibliographies for each chapter and up-to-date census figures. The featured languages have been chosen based on the number of speakers, their role as official languages and their cultural and historical importance. Each language is looked at in depth, and the chapters provide information on both grammatical features and on salient features of the language's history and cultural role.
