A few! A Revolutionary Reading List - Audiobooks, Book Club Commune, Book Clvb(with the v on purpose), Foreign Languages Press - Audiobooks, Leftist Reading, Red Book Club, Socialism For All S4A. The last one isn’t exclusively audiobooks, but it’s got a bunch. I think it’s a YouTube channel, maybe. I also just make sure to search anything I’m interested in any time I hear about it. It may be on a podcast that’s geared toward books in general that I wouldn’t have found without a specific search anyway. Other times, people will make a podcast just for one book. I go back and look again anytime I hear of something I haven’t found yet just in case someone’s put it up.
