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.

ScienUsts have been investigating the porpoise as the representative of an alien
intelligence, seeking to communicate with it, seeking to understand what alien
intelligence can b1~ like. The porpoise's deeply convoluted brain is larger than
man's.
Golay, M. J. E. Coherence in interstellar signals. IRE Proceedings, v. 49, 1961:
958-959.
It is stated it would appear theI'e are four likely spectral regions within which
a search should be made for coherent signals before any intelligent messages
can be received: at half or at twice the hydrogen frequency, and with or with-
::Jt correction for nebular drift. When factors such as easier power genera-
tion and greater space coverage are considered, the two half -frequency regions
appear more favorable.
----- Note on the probable character of intelligent radio sig'lals from other plane-
tary s:tstems. In Proceedings of the IRE, v. 49, May 1961: 959.
Discussed are the spectral location and the character of racio signals that might
be aimed at the earth from other planets of other solar systems.

46-47, 96.
Author discusses what space travelers from earth might say--if they can find
a way to say it--to alien intelligent beings they might discover in the universe.

Estimate of the probability of communi.cation with intelligence in outer !:1paLe is
beset with many unknown factors, the author postulates. Sifting through these,
the probability that a c;:;;-;-.i11unicating c:v~lization has existed at some time is
assigned a value of between 2 X 10-2 and 10-6 for any star. To receive a sig-
nal from at least one civilization within 1,000 light years, it is estimated that
examination of some 2 X 105 likely stars in a field of about 107 stars is re-
quired, a longevity of 50,000 years, and no previous int~rcommunication. The
recommended .;·gnal to search for is a high-intensity, narrow-band transmis-
sion at or near the 21 cm. hydrogen frequency.

It is stated that beings who are transmitting signals to other worlds, in order
to increase their chru1,~es of contacting civilizations in other worlds, must di-
vide the antenna time and beam the signals successively to all stars which are
