The Oxford Handbook of Sociolinguistics will differ from existing work in four major respects. First, it will emphasize new methodological developments, particularly the convergence of linguistic anthropology and variationist sociolinguistics. Second, it will include chapters on sociolinguistic developments in areas of the world that have been relatively neglected in the major journals. Third, its chapters are written by contributors who have worked in a range of languages and whose work addresses sociolinguistic issues in bi- and multilingual contexts, i.e. the contexts in which a majority of the world's population lives. Finally, it will include substantial material on the rapidly growing study of sign language sociolinguistics.
