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 Sébastien 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. It is a perfect reflection of the openness of anarchism, an unequaled assembly of the riches of the movement, and an essential text that has sadly been unavailable in English. Although much shorter, our selection reflects the depth and range of the original. Abidor's lengthy Introduction provides historical context, biographical detail about the contributors, and an overview of political philosophies covered.
