This is an abridged version of the Anarchist Encyclopedia. The original was a four-volume compendium of anarchist thought and analysis compiled by the great anarchist activist and writer Sebastien Faure. Within its pages can be found articles on political, social, and philosophical questions written from every point of view within the anarchist movement and by many of the most important figures of anarchism, like Faure, Max Nettlau, Emile Armand, Voline, and Errico Malatesta.
