Right -- for example, the "Joking" and other stories are written by Ralph Leighton[1]. Interestingly, Ralph is son of Robert Leighton[2], the caltech physicist who was a contemporary (and peer) of Feynman's and part of the team that transcribed and edited "the Feynman Lectures". So that's 2 (or 3) of the big books that feynman's said to have written that he was only partially involved with. And lastly, if my dad were a physicist and I went out of my way to write a book about another physicist, and I went out of my way to describe that other physicist as the best and most coolist physicist ever, there's probably an interesting backstory that's not in the book.
