Anarchism for Beginnersgoodreads
Nice historic overview that can be handled in several hours. I was disappointed with the emphasis given to the bombings and assassinations and extreme brevity of anything after ww2 (in total less then 10 pages). The first part (the 19th century) is ok as an introduction to the topic I guess.
As an excellent introduction to anarchism I would suggest On Anarchism by Noam Chomsky, especially it’s first two sections.
