With world-wide environmental destruction and globalization of economy,a few languages are spreading rapidly in use (especially English), while thousands of other languages are disappearing, taking with them important cultural, philosophical, and environmental knowledge systems and oral literatures. We all stand to suffer from such a loss, none more so than the communities whose very identity is being threatened by the impending death of their languages. In response to this crisis, indigenous communities around the world have begun to develop a myriad of projects to keep their languages alive. This volume is a set of detailed accounts about the kind of work that is going on now as people struggle for their linguistic survival. It also serves as a manual of effective practices in language revitalization.
