Thanks, Jim! I certainly agree that multiple proofs deserve Bookhood (and some clearly don’t). This is a great example, especially given your comments about how each proof has different power to generalize. I think you should do a column sometime on the Devil’s book — the book of mathematical truths that are easy to state, but which have no proof in God's book. Perhaps the 4-color theorem is one of these… - Cris
