Can someone educate me on anarchism?

[foal]

Since there are so many ACs on twoplustwo, I would like to get a better sense of what it is. I.e.
Any good books you would recommend on the subject (hopefully something that takes reality into account)?
Is it just a more extreme form of libertarianism?
What form of anarchism do "typical" anarchist kids subscribe to? Like the kids who graffiti (A) signs and protest at free trade conventions?
What is the process people would go through to "own" land in an AC system (besides buying from someone who already owns it)?
