I'm completely reminded of the book I read recently, How They Croaked. This has the same dark humor, the same quick facts, and the same interesting ideas. While so far I've found this better then the other book...I'm meeting with the same issue of no footnotes and no way to easily track sources. Most I've found to be true to the best of my knowledge...but others I'm unsure of.
I think this would be a great supplemental text for a history class though.
