Atlases and Gazetteers
Atlases and Gazetteers will come in handy when your research requirements contain a geographical component.
In addition to maps, many atlases include specialized information regarding the history, natural resources, ethnic groups as well as a wide variety of other topical subjects regarding specific countries and regions of the world.
Gazetteers, like the Columbia Lippincott Gazetteer of the World, contain alphabetical listings of place names and provide basic information such as location, recent population figures and the physical and cultural features that distinguish them.
The online U.S. Gazetteer, for instance, published by the U.S. Census Bureau, provides precise latitudes and longitudes of any place-name entered into its search field.
