Advance praise: 'There are lots of things we don't know about variation in English, but the authors of this book know more than just about anyone!' Peter Trudgill, Agder University 'This book provides a broad overview of the study of variation in English. Contributions are concerned not only with the traditional issues of reliable data collection and appropriate methods of analysis, but also with the relevance of linguistic variation to linguistic theory and related areas of applied linguistics, population genetics and education. It will be a useful resource both for students of linguistics and for interested colleagues.' James Walker, York University, Toronto
