Someone is borrowing my pmm d&t book (Nathan Coppedge's Perpetual Motion Machine Designs & Theory) from the Newton Free Library now...
Some people, however, may want to own it for themselves. It's my most popular book (about 90 copies sold to date). Link here: http://www.amazon.com/Nathan-Coppedges-Perpetual-Machine-Designs/dp/1495373835/ Ignore the three-star reviews. It's one of the best books on perpetual motion.
