U.S. Library of Congress. Books in this series present a description and analysis of the historical setting and the social, economic, political, and national security systems and institutions of select countries throughout the world. Most books in the series deal with a single foreign country, but a few cover several countries or a geographic region.
The series includes several books on countries that no longer exist in their original configuration—such as Czechoslovakia, East Germany, the Soviet Union, Sudan, and Yugoslavia. These books remain in the series because they continue to offer valuable historical information and perspective. In some cases, studies on successor states are also part of the series.
U.S. Department of State. Facts about the land, people, history, government, political conditions, economy, and foreign relations of independent states, some dependencies, and areas of special sovereignty.
U.S. Central Intelligence Agency. Information on the history, people and society, government, economy, energy, geography, communications, transportation, military, and transnational issues for 267 world entities.
