The Georgia Official and Statistical Register, published from 1923-1990 by the Georgia Department of Archives and History, is commonly known as the Georgia Blue Book.
Considered an important reference work for historical research, the Register covers Georgia's executive, legislative, and judicial branches of government, providing biographical sketches of elected and other state officials. Georgia members of U.S. Congress and federal judges are included, as are county officials and regents of the university system. The Blue Books contain election returns, provide basic reference data on Georgia counties, and cover Georgia miscellanies, such as the state flag, state flower, state song, rosters of Georgia governors, and legal holidays.
