animal farm is a fantastic political book, and there was this other book that was amazing but i cant remember the name, another member recommended me.
a good one is the anarchist cookbook, even though its a little outdated.
I cant' really refer you to a whole lot of book on anarchy, but I know a few with an anarchic undertone...
Currently, I'm reading Ender's Game (I have no idea if it has anything to do with anarchy, but Ive only heard good things about it)
Fight Club and Choke are really good. (Chuck Palinuik is pretty awesome) (Made into moves)
One Flew Over the Cuckoo's Nest (Also made into a movie)
Although I havent been able to get my hands on it (yet) "Steal This Book" looks good.
Fahrenheit 451
I'm currently going blank on the books Ive read now...if I remember anything else I'll post it.
