Investing Books - What's Your Dad's Book?

An old book by a guy named Edgar Cherry called Redwood in California Forests. And there's only 37 known copies in the world and I own three of them. You have to take any of those books like that and kind of adapt them in your mind for all of the modern technology. The principles largely apply if you extract away, how would you have done things then with a pencil versus today with a computer?
