Anarchy Works takes examples from around the world, combing through history and anthropology, showing that people have, in different ways and at different times, practiced mutual aid, self-organization, autonomy, horizontal decision-making: all the principles that anarchy is founded on, regardless of whether they call themselves anarchists. Well documented and expansive, this book is an inspiring answer to those who would say that anarchism is unrealistic, that it sounds nice but it couldn't actually work. This point-by-point introduction shows that it already has.
