The Columbia Gazetteer of the World Online contains over 170,000 articles or entries on all types of places throughout the world; both physical places and political entities. Most articles have details on where the place is located, its dimensions and borders, and information on economic activities, demographics, history, and former or alternate names and different spellings and pronunciations. More advanced researchers will be able to make use of new tools to extract data, both current and historical, from the Gazetteer database and reformat and reuse that data in other applications.
