Although a number of edited collections deal with either the languages of the world or the languages of particular regions or genetic families, only a few cover sign languages or even include a substantial amount of information on them. This handbook provides information on some 38 sign languages, including basic facts about each of the languages, structural aspects, history and culture of the Deaf communities, and history of research. This information will be of interest not just to general audiences, including those who are deaf, but also to linguists and students of linguistics. By providing information on sign languages in a manner accessible to a less specialist audience, this volume fills an important gap in the literature.
