After the export of indigenous material was restricted by the Act of November 1913, a collection intended for Cologne's Rautenstrauch-Joest Museum was impounded at Port Adelaide, and was purchased by the South Australian Museum. Strehlow's genealogical records of long-dead Aranda men and women dating back to around the beginning of the nineteenth century are possibly the most exhaustive for anywhere in Australia and of priceless value to their descendants today: unfortunately they were heavily cut when published, but the originals survive in the Strehlow Research Centre in Alice Springs.
