Extraterrestrial Intelligence and Unidentified Flying Objects: A Selected, Annotated Bibliography

This document is a selected, annotated bibliography prepared by Marcia S. Smith of the Congressional Research Service, dated February 18, 1976. It serves as a companion to two other Library of Congress publications: 'The UFO Enigma' and 'Possibility of Intelligent Life Elsewhere in the Universe.' The bibliography is divided into two primary parts: Part I, which focuses on Extraterrestrial Intelligence, and Part II, which focuses on Unidentified Flying Objects (UFOs). The author notes that these two fields are separated because, while interrelated, many researchers in the field of extraterrestrial intelligence do not believe Earth has been visited by such beings and do not rely on UFO reports for their conclusions. The bibliography includes a wide range of sources, including books, magazine articles, and government reports published up to 1976. The author acknowledges the foundational work of Lynn Catoe, whose 1968 bibliography provided many citations for pre-1969 works. The entries cover a diverse spectrum of perspectives, ranging from scientific and academic discussions on exobiology, interstellar communication, and radio astronomy (such as Project Ozma and Project Cyclops) to more speculative and controversial literature regarding UFO sightings, contactee accounts, and government involvement. The document includes entries for major reports such as the Condon Report and various congressional hearings. The author notes that private publications, such as those by James McDonald, were included with some reservation due to their potential difficulty to obtain. The bibliography is intended to be representative of the literature and accessible through local libraries, providing a structured overview of the discourse surrounding extraterrestrial life and UFOs as it existed in the mid-1970s.
