Most people are unaware of the existence of the Australian Dictionary of National Biography, a remarkable effort of scholarship by an army of volunteer historians and specialist contributors committed to documenting significant and representative Australians. It’s a challenging task in terms not only of scale but because previous entries need to be revised in the light of fresh historical evidence and interpretation. Women and First Nations figures were overlooked when the project began, but that is now being addressed.   The Director of the National Dictionary of Biography is historian Dr Melanie Nolan. She tells Life Sentences how the Dictionary differs from its British counterpart, how entries are selected and how the Dictionary is trying to move with the times.
