Marxist online recources

i personally had a hard time finding accurate non-propaganda sources on marxism online so here are some that i have found over time: 

marxists.org

large library of communist, anarchist, and other revolutionary thought, online. 

oceanofpdf.com

free epubs in general, has a large amount of political theory. 

marxist.net 

articles on science and philosophy and how they connect to marxism, recources like the manifesto, and other core books, and links to communist news websites. 

marxistsociology.org

news articles on topics relevant to the revolutionary spirit, a QNA section answering common questions about marxism, and reviews of pre-existing theory. 

correct me if any of these are dodgy.
