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.

Results of 1953 study of UFOs by committee chaired by H. P. R'lbertson, theo-
retical physicist at California Institute of Technology. Examination of distribu-
tions of important characteristics of sightings and study of sightings evaluated
as ''unknown" led to conclusion that a combination of factors, principally the re-
ported maneuvers of the objects and unavailability of supplemental data such as
aircraft flight plans or balloon-launchir.g records, resulted in failure to identify
as ''knowns" most of the reports of objects classified as "unknowns. "
