According to Bowditch Vol. 1, 1977 Edition, page 586: "Pub No 249 *Sight Reduction Tables for Air Navigation*, in three volumes, are published by the defense Mapping Agency Hydrographic Center. A preliminary edition of Volume 1 for selected stars was published in 1947 under the title *Star Tables for Air Navigation*...by the time the "first" edition was printed in 1951, for epoch 1955.0 more the 20,000 copies of the preliminary edition had been distributed."
