The best deal is to buy the $6 E-book. It downloads to your computer in about six minutes. Unfortunately, the back cover, which is full of handy information, was not included in the E-book, but otherwise it is exactly the same as the paperback. If you want to print out any of the maps, be aware that for printing purposes the computer counts the unnumbered pages at the beginning of the book, so add eleven pages to the page number shown on the screen and preview it first to be sure you have the map. You can order the book from any E-book dealer on the internet or from iUniverse.
