This is Government Attic's posting of a 1969 Library of Congress annotated bibliography, UFOs and Related Subjects, compiled by Lynn E. Catoe for the Air Force Office of Scientific Research. The Defense Technical Information Center released it under FOIA in November 2014. The bibliography lists more than 1,600 items and was requested to support the University of Colorado UFO study led by Edward U. Condon. Its preface concludes that no simple, single explanation of the UFO phenomenon applies to all cases.

A broad general view of the chief mysteries and problems of astronomy is given; possibility of life and intelligence on the moon and on Mars is discussed. Sewall, Frank.

Astronautics, v. 5, Apr. 1960: 32-33, 50, 52. It is postulated that homo sapiens as a species may be unique, but there is good reason to expect that there are habitable planets with higher forms of life in other soJar systems. ----- Riddle of God, man and outer space.

Includes study oi earth's solar S~'S tem, discussion of nature of life and its possible occurrence on other planets, treatment of pos~ibility that advanced commuriicative technical civilizations exist on planets of other stars, and discussion of problems in establishing con- tact with civilizations separated from earth by interstellar distances. Simpson, George G. The nonprevalence 0f humanoids. Science, v. 143, Feb. 21, 1964: 769-775. States following conclusions: (1) there are certainly no humanoids elsewhere in the solar system of which earth is part; (2) there is probably no extraterrestrial life in the solar system of which 1~arth is part, but the possibility is not wholly excluded as regards Mars; (3) there probably are forms of life on other plane- tary systems somewhere in the universe, but if so it is unlikely that we can learn anything whatever about them, even as to the bare fact of their real exis- tence; (4) it is extremely improbable that such forms of life include humanoids, and apparently as near impossible that we could ever communicate with them in a meaningful and useful way if they did exist.
