I’m thinking of dumping Posner. Skimming Bugliosi shows he’s fairly dismissive of it, accusing it of misquotes and factual distortions. Since they reach the same conclusion, and B’s book is much more extensive, I may save myself reading 600+ pages. Also it turns out I do have B’s CD-rom, with its 1000+ footnotes. It was tucked inside the front cover, not the back, where I’d expected it.
