IN WRITING THIS BOOK I have kept footnotes to a minimum, because most of my new material is from Mongol and Russian sources. Fortunately, however, Mongolia is by no means a closed country, and fairly recent material is also available in other languages. A number of the books listed below have bibliographies, which widen the field indefinitely for those who want to go on reading about Mongolia.
National Economy of the Mongolian People's Republic for Forty Years, A Collection of Statistics, Ulan Bator, 1961. There are two editions, one in Russian and English, one in Mongol and Russian.
Harrison Salisbury, To Moscow and Beyond, New York, 1960. The author is a correspondent of the New York Times.
Gerard M. Friters, Outer Mongolia and Its International Position, Baltimore, 1949. (Introduction by Owen Lattimore.) The most useful summary of treaties, diplomatic notes, and official statements.
Ivor Montagu, Land of Blue Sky, A Portrait of Modern Mongolia, London, 1956.
