Lois Tilbrook's important work, Nyungar Tradition : glimpses of Aborigines of south-western Australia 1829-1914 which is now out of print has been published by the Australian Institute of Aboriginal and Torres Strait Islander Studies (AIATSIS) as an electronic book.
In their introduction to the site, AIATSIS says:
Nyungar Tradition by Lois Tilbrook is based on the South West Aboriginal Studies project (SWAS) - in which photographs have been assembled, not only from mission and government sources but also, importantly in Part ll, from the families. Though some of these are studio shots, many are amateur snapshots. The main purpose of the project was to link the photographs to the genealogical trees of several families in the area, including but not limited to Hansen, Adams, Garlett, Bennell and McGuire, enhancing their value as visual documents.
The AIATSIS Library acknowledges there are varying opinions on the information in this book.
