Country Studies, formerly known as Army Area Handbooks, were issued within the Department of the Army. Each handbook discussed a country's social system (history, geography, ethnic groups, religions); political system (form of government, foreign relations); and economic system (trade, agriculture, economic structure). Over 100 countries were each covered in a handbook and most of the handbooks were periodically updated. The handbooks now provide historical information and perspective.
