Survival books to keep on your bookshelf in case of the apocalypse

Survival books to keep on your bookshelf in case of the apocalypse: "When the apocalypse strikes, you probably won't have access to the Internet. That means no Google, no Wikipedia, and, if you haven't prepared, no cheat sheet to help you through the tough times. Here are a few books you might want to have on hand in case the worst happens. Just remember to keep a back-up pair of glasses in your emergency kit."
