Cambridge University has launched a project (the World Oral Literature Project) to create records of some of the world's dying languages. Speakers of these languages are being encouraged to record their songs and myths using multi-media tools. The languages include the Barasana language of Colombia and Lowa, spoken in Nepal. The project concentrates on non-Western languages and cultures, even though, as one of the researchers admitted, there are pockets of threatened languages in the UK and Europe too (Cornish, Breton, eg).
