The little giant encyclopedia of UFOs

This encyclopaedia covers every aspect of the UFO mystery, including all the key dates and events.

It assesses the various categories of sightings, close encounters, abductions and time lapses.

An A to Z atlas maps the global differences in government attitudes, scientific research, types of activity and numbers of sightings; an alphabetized listing covers major researchers, authors, groups and publications; and there's a directory of world records.
