From Jared’s review:
For those who can read Russian, Vadim Damier’s two-volume study of the International Workers’ Association (IWA) is a comprehensive history of the worldwide anarchist labour movement in the early 20th Century. For the rest of us, Malcom Archibald has translated what is essentially a streamlined version of Damier’s larger work into English. Anarcho-syndicalism in the 20th Century is a broad survey of a movement often marginalised by Marxist academics, and is a welcome addition to the existing literature on anarcho-syndicalism. As Damier illustrates, anarcho-syndicalism was far from a outmoded, ineffective or petty-bourgeois movement — the practice of direct action and revolutionary struggle controlled and self-managed by the workers themselves extended to all countries of the world.
