From the Library of Congress, "Contains the electronic versions of 80 books previously published in hard copy as part of the Country Studies Series by the Federal Research Division. Intended for a general audience, books in the 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."
