Lessons from History is a big, ambitious book. Its twenty-two essays – amounting to some 400 pages of research, reflection, and references – seek to pin down, in accessible form, the combined expertise of thirty-three practitioners of history and related fields. Together they address a mélange of pressing issues facing Australia today, testament to the diversity of contemporary Australian history and its interdisciplinary reach. Political, social, economic, business, environmental, and oral historians are all represented, alongside authors whose institutional base is in strategic studies, economics, politics, or administration, but whose work is informed by a keen interest in the past and its lessons.
