Okay, sticking with the time travel theme. In the 1960 classic film, The Time Machine, based on HG Wells' novel there is a mystery left at the end. The Time Traveller (played by Rod Taylor) gets back in his machine and returns forever to a future with the illiterate Eloi and the degenerate cannibals, the Morlocks. To rebuild the shattered world, he takes with him three books from his library. His friend Philby inquires of the housekeeper "What three books would you have taken?" So, to rebuild the future, what three books would YOU bring?
