He's a former professor as well, other user hit all the points about him. I still recommend his Super Imperialism if you ever get the time, yes there is some radlib Trot horseshittery quips in there but its not significant as say some of Harvey's pieces, its a heavy geopolitics economics text and reading you can feel the textbook level hit you.

I haven't read the new edition though. As with this piece he repeats himself a lot, tendency of old school lecturers. He also prefers to make his work in print over digital, so it makes looking for his work on the internet a bit challenging.
