I read the penguin classics version, with a 270 page introduction about the political backdrop for the manifesto, the things that influenced and inspired it, and its impact on history. I would strongly recommend reading this so the text itself makes more sense.
I am very happy to have read it. In some ways, it's an antiquated text now, dated with the way it doesn't identify colonialism as a part of white bourgeoisie interests. I didn't agree with everything, and would likely call myself an anarchist rather than communist after having read this, but I feel deeply informed and ready to read further.
