Summary from site:
The Southwest Pacific from Southern China through Indonesia, Australia and the Pacific Islands constitutes the richest linguistic region of the world. That rich resource cannot be taken for granted. Some of its languages have already been lost; many more are under threat. The challenge is to describe the languages that exist today and to adopt policies that will support their maintenance.
