You can buy small booklets or ‘pocket guides’ from building supply centers that show the main steps of construction. Besides being compact and low cost, the nice thing about these pocket guides is they only show want you really need. Many homeowners don’t need a full length book on these subjects. They just need to know the basics. Pocket guides (the lowest cost versions) have simple black and white line drawings of each main step. For instance, pocket guides illustrate how to wire an outlet or a switch.
