Ida Pilat Isca's translation of A Short History of Anarchism - a comprehensive, one-volume introduction to the origins of the idea of anarchy and the emergence of the modern anarchist movement - is a particular treasure. Written to indicate the breadth and diversity of anarchist ideas and practices, in a style that largely allows the historical facts to speak for themselves, it remains remarkably useful and current, despite the years that have passed since its composition in the 1930s. Nettlau's historical account is supplemented by biographical and bibliographical resources - some new to this edition - which aid both readers and researchers interested in navigating the broad river of anarchy.
