New in paperback. Hardcover was published in 2007. The encyclopedia records those languages which, for whatever reason, are not being passed on to younger generations. It lists all known endangered languages, continent by continent, and describes their situation. Edited by internationally regarded specialist Christopher Moseley, co-editor of the classic Atlas of the World's Languages, this is an essential resource for linguists, language-lovers, and anyone who believes that the human community is impoverished by the loss of even one language.
