Over the past decade, an increasing number of linguists have been turning their attention toward the plight of endangered languages. We are realizing that most of the small indigenous languages of the world are in great danger of disappearing over the coming century, if they have not already disappeared. Nor are linguists alone in their concern; the media have become interested in the issue, as have international organizations – like UNESCO, the European Union, and even national governments that have in the past been instruments of the demise of indigenous languages. Clearinghouses are being set up (e.g. the International Clearing House for Endangered Languages at Tokyo University), and funds such as the Endangered Languages Fund. Most active in fighting language extinction are members of the affected communities themselves, who are working on their own, or forging new kinds of partnerships with linguists, in an effort to reverse language shift. In the context of these movements, this excellent book is a welcome and crucial resource. The volume gathers together a set of valuable articles by a group including some of the best scholars in linguistics and some of the best native language teachers: Nancy Dorian, Nora and Richard Dauenhauer, Kaia'titahkhe Annette Jacobs, Colette Grinevald, Marianne Mithun, Ken Hale, Christopher Jocks, Anthony Woodbury, Carol Myers-Scotton, and Nikolai Vakhtin. It is a must-read for anyone – native, linguist, teacher, or policy maker – who is involved with issues of language loss, maintenance, or revitalization.
