Skirda reviews the attempts at large "mass" type anarchist organizations in France, Russia and Spain. Throughout the book, he argues for the creation of an anarchist international federation, complete with elected representatives and what have you, and deplores the anti-organizationalist tendencies which have worked against such a federation. I learned a lot from this book, and actually enjoyed much of it. It had many fun and interesting anecdotes, and the writing is engaging and personal. Nonetheless, I cannot in good conscience give it a high score. For one thing, the selection criteria seem scattershot and arbitrary. It clearly reflects Skirda's conviction that revolutionary, mass organization of the platformist kind is the only thing that matters. But what really mars this work is the lack of charity with which Skirda treats all the anarchists who have historically critiqued his preferred form of organization. It's fine that he is a platformist, and it's good that he is upfront about that - but every anti-organizationalist, individualist, and insurrectionist critique is brushed aside and misrepresented without serious engagement. What's most infuriating, Skirda engages in recurring copjacketing, at several points dishonestly implying that illegalists, individualists and propagandists of the deed were probably agents of the state, without stating it outright!
Above all, I just feel it's so important to state that this is not a well-rounded history of anarchism, and I'm slightly horrified at the thought of someone new to anarchism picking it up as an introduction. Such a reader I implore to check out alternative schools of thought within anarchism, including but not limited to individualist anarchism, market anarchism, insurrectionary anarchism and anarcho-feminism. For the anarchist geek who wants to chuckle at a century of scene drama, this is worth the read, though.
