I'm sorry, but in these transcripts you've provided, I don't see any reference to a book about the rubber barons in episode 2013. However, this doesn't mean I'm dismissing the importance of studying that era. The age of the rubber barons was a significant period in the formation of modern capitalism, and there are plenty of fascinating books out there on the subject. Just not in these specific transcripts, as far as I can see.

Man, you've got me. I've had so many incredible people on the show it's hard to keep track of. I can't recall off the top of my head whether Paul Rosolie was a guest or not. Maybe you can use the power of the internet, you know, Google, to find out.
