A good atlas should be on your bookshelf along with a dictionary, thesaurus, and other references. An atlas has a way of going out of date more rapidly than a dictionary, so it's important to have one that is current, but does not cost a fortune. This volume fills the need wonderfully. The maps are detailed and easy to read. New nations are there, and there are excellent maps of the terrain throughout the world. You can sit in your armchair and travel the world with these remarkably clear maps. There is a huge index of cities and clear information about climate and population around the planet. All this, and the price is amazingly low. It's an excellent atlas for a bargain price.
