Used books are cool. Same great content, low low prices. I picked up 5 new books this weekend, all for about $30. I got a great old 2 volume copy of Outline of History by H.G. Wells, an old copy of Darwin’s The Origin of Species, Full House by Stephen Jay Gould, and a crazy book called Techniques of Revenge, published by Loompanics, a company that publishes books on all sorts of strange topics, from guerilla warfare to bypassing burglar alarms.
