'This issue leads with Marcia Langton's Wentworth lecture delivered on 26 March 1992 at the Australian Academy of Science, Canberra. The Wentworth lectures were inaugurated in 1978 as a biennial series to honour the contribution of the Hon W C Wentworth to the establishment and development of the Australian Institute of Aboriginal and Torres Strait Islander Studies. Former Wentworth lecturers are Dr Rhys Jones, Ms Margaret Valadian, the late Professor R M Berndt, Dr LR Hiatt, Professor DJ Mulvaney, Mr Ken Colbung and Dr Nicolas Peterson. It is customary to publish the Wentworth lecture in Australian Aboriginal Studies.  (Editorial introduction)
