It's a great history of anarchism, but I suppose I should have looked into it more before starting it because I was hoping for an actual outline of anarchist ideas - i.e., how things like factory councils and land collectivization would actually work. Guerin assumes knowledge of these things and then looks at specific successes and failures in their implementations throughout the past 100 or so years. So if that's what you're looking for it's an incredible work! I'll probably go and read some Bakunin, Proudhon, and Kropotkin before returning to this one.
