For books anyway, the two books people recommend are Blackshirts and Reds and Inventing Reality. For lectures, there’s Yellow Parenti (just search for yellow parenti on Youtube).

I also like his series of lectures called Real History. There’s a playlist here (ignore the random Fortnite video at the end): https://invidious.protokolla.fi/playlist?list=PLZdjCqT95Peq3KzB0hU2b_BOi5BF2nmkj

It’s split into 5 parts:
Part 1: The Myth of the Founding Fathers
Part 2: The Spanish American War and the Rise of US Imperialism
Part 3: The Functions of Fascism
Part 4: The Real Causes of World War II
Part 5: Psycho-history
