All the material is written in Japanese, covering a wide range of subjects, including languages, beliefs, ceremonies, and hunting. The database is drawn from 30 renowned journals of the time: The Journal of the Anthropological Society of Tokyo , Taiwan Folklore, Journal of Anthropology, and Taiwan Times, to name but a few. All the articles give vivid portraits of Taiwan 's aboriginal tribes in the early 20th century. This database should be of great help to those doing advanced studies on Taiwan aboriginal culture.
