An atlas is a collection of maps, generally bound into book form but may also be found in multimedia formats, such as a CD-ROM. As well as including information about geographic features and political boundaries, many often feature geopolitical, social, religious and economic statistics. World atlases can vary greatly in size and comprehensiveness, ranging from pocket world atlases to immense books that need a full sized table to support them when they are open.
Choose one to suit your needs - do you want a handy compact reference book for your desk or are you a serious map-lover who wants to pore over detailed maps and information? Are you looking for simple, general information about the countries of the world, or are you interested in learning about the politics, economics, religion and climate of a country?
