Since no one answered this, I'll recommend the Jon Lee Anderson biography of Che. It is authoritative even though it's not by a professional historian and is worth reading despite its length. When this appeared in 1997 the literature on Che was really spotty, and this book added a huge amount to our understanding of the man. He gained exclusive access to a lot of archival sources and traveled the globe interviewing Che's surviving allies and enemies.Zumpano wrote:What should be required reading before I see it?
He presents a fairly good understanding of Che's ideas even though he does not always agree with them, and he looks at the Revolution in the last few decades with a critical eye.
I'm also recommending it because it's an easy book to find and also a pretty inexpensive one.
