'In sum, this volume deserves to be warmly welcomed by scholars of Popper. Summing up: Reommended' - CHOICE'This book is excellent. It is largely unpublished material from Popper’s literary remains regarding his The Open Society and Its Enemies that conveys some interesting stories about its publication and initial reception, throws light on its message, and complements it somewhat. The book also contains much that Popper hardly discussed elsewhere.' - Philosophy of the Social Sciences'[an] expert selection of archival materials and obscure publications...' - ISIS
