The Ara Irititja Project
This project is maintained by the Anangu of Central Australia. Its name means "stories from a long time ago" in the language of that people.
"The aim of Ara Irititja is to bring back home materials of cultural and historical significance to Anangu. These include photographs, films, sound recordings and documents. Ara Irititja has designed a purpose-built computer archive that digitally stores repatriated materials and other contemporary items."
This is a rich source of oral histories from the Koorie, a people from Victoria and New South Wales in Australia.
