Three books that Jeff Bezos had Amazon's senior execs read

Jon Fortt of CNBC interviewed Jeff Bezos a while back, doing the whole PR thing about the new Kindle Fire models, which wasn't all that interesting. But in the process, Bezos mentioned that he had
hosted three all-day book clubs with Amazon's top executives.

Which books did they read? Bezos doesn't say, but Fortt does:

The Effective Executive by Peter Drucker
The Innovator's Solution by Clayton Christensen
The Goal by Eliyahu Goldratt
