This paper aims to analyze the importance of reading and of the book in the context of anarchism in the 1930’s in Spain. No study of the history of reading can be complete without an analysis of written productions, the way access was provided to content, the reading tastes of the affiliated members, and the internal issues that defined those publications. The book is considered an object of cult and admiration because it allows individuals to shape a free culture against power. Hence, the book was considered a moral liberator tool that workers had to use to shape a true revolutionary consciousness. The Libertarian Athenaeums and the anarchistic press stood out as the main dissemination channels of all types of works dealing with different topics among their affiliates and sympathizers.
