Suggestions from Steven Bird:

I guess there's a sequence of three readings that might set the scene for an interesting discussion on language technologies for endangered languages.
1. Why collecting bilingual texts on a large scale is a good idea: The Human Language Project: Building a universal corpus of the World's languages (Abney & Bird, ACL 2010)
2. How to do such collection for a small language: A scalable method for preserving oral literature from small languages (Bird, ICADL 2010)
3. Some ideas about language technologies to support this (Bird, LiLT 2010?)
