This book presents in a single volume a comprehensive history of the language sciences, from ancient times through to the twentieth century. While there has been a concentration on those traditions that have the greatest international relevance, a particular effort has been made to go beyond traditional Eurocentric accounts, and to cover a broad geographical spread. For the twentieth century a section has been devoted to the various trends, schools, and theoretical framework developed in Europe, North America and Australasia over the past seventy years. There has also been a concentration on those approaches in linguistic theory which can be expected to have some direct relevance to work being done at the beginning of the twenty-first century or those of which a knowledge is needed for the full understanding of the history of linguistic sciences through the last half of this century. The last section of this book reviews the applications of some of these findings. Based on the foundation provided by the award winning Encyclopedia of Language and Linguistics this volume provides an excellent focal point of reference for anyone interested in the history of the language sciences.
