As pocket references go, this new one has a lot of advantages others miss. The book's spiral binding makes it ideal for tossing in a toolbox or dropping in an apron pocket. The fact that it opens flat to lay on a work surface for easy reference, is a big plus. It is a book to take along to the lumberyard or hardware store, or keep in the shop for quick answers to confounding formulas and cutting crown molding angles; well worth having. For me, the mark of a good reference guide is one that you don't have to spend an eternity studying, and Charlie draws upon all his experience to present a book that will ensure more time in the workshop and less time flicking through pages to find solutions to woodworking problems.
