I am looking for good books that explain the relationship between anarchism and communism, and how they differ in practice. I am not looking for a book that takes a communist angle and calls anarchism merely utopian or a liberal version of communism that has no revolutionary potential, or the liberal anti-communist propaganda that calls itself anarchist or radical and mostly serves to spread the lie that Stalin was actually worse than Hitler.

I have had trouble finding books that do not approach each other from this lens but instead takes you through historical examples where both groups disagreed and why, and when there has been clear unity in the fundamental goal of communism and anti-capitalism
