Library of Congress Country Studies
'This website contains the on-line versions of books previously published in hard copy by the Federal Research Division of the Library of Congress under the Country Studies/Area Handbook Program sponsored by the U.S. Department of Army. Because the original intent of the Series' sponsor was to focus primarily on lesser known areas of the world or regions in which U.S. forces might be deployed, the series is not all-inclusive. At present, 102 countries and regions are covered. Notable omissions include Canada, France, the United Kingdom, and other Western nations, as well as a number of African nations. The date of information for each country appears on the title page of each country and at the end of each section of text.'

USGS Geographic Name Information Service (GNIS)
'The Geographic Names Information System (GNIS), developed by the USGS in cooperation with the U.S. Board on Geographic Names (BGN), contains information about almost 2 million physical and cultural geographic features in the United States and its territories. The Federally recognized name of each feature described in the data base is identified, and references are made to a feature's location by State, county, and geographic coordinates. The GNIS is our Nation's official repository of domestic geographic names information.'
