History of the All-Union Communist Party (Bolsheviks): Short Course

👍 or 👎?

I'm surprised that it took me this long to stumble on this book, by chance, and that it's not mentioned anywhere when looking for introductory reading. Everyone seems to compile their own reading list on introducing people to ML, but no one mentions that the CPSU went to great lengths to create their own "definitive" introduction. Which kinda begs the question why is it not mentioned (seemingly) anywhere?
