Vichy France and the Resistance [PDF ebook] 
Culture and Ideology

This book, first published in 1985, examines various aspects of the intellectual achievements of writers and artists in the Vichy period; a strong emphasis on the ambiguity of much of their work emerges from the research. It goes a long way in answering the question of what it was like living under the fascist Vichy regime, and what the collaborators and resistance thought about their purpose and patriotism.
