The UFO Phenomenon is a typical, if not representative, volume of Time-Life's Mysteries of the Unknown series; however, in order to avoid repetition, I will redirect the reader to a review of a similar, but ever so slightly worse, Mysteries of the Unknown text, a certain Psychic Powers. While the subject matter of the two works does, indeed, differ, the two volumes are very much the same in terms of their extremely relative levels of sentimental and practical value. ( )
