  GEODE The US Geological Survey has created an excellent resource in its GEODE site (GEO-Data Explorer). This Web-accessed GIS (geographic information service) server presently provides some 67 maps of varying complexity from multiple locations around the world (46 of which are regional maps of the US).

  GeoExplorer This British site "aims to meet all ... geographic needs ... to support students and teachers of geography or those with a general interest in geography." The site addresses those needs admirably with its wonderful collection of data and abundant links to information about all aspects of geography and geosciences.

• 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, 101 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 secion of text."
