Doubleday & Company, Inc., Garden City, New York, USA, 1979. – 311 p. – ISBN: 0385143486.
The UFO Handbook is a great "how-to" guide for the UFO investigator, listing tools, techniques, and procedures of inquiry. The first third of the book covers IFO's (Identified Flying Objects), with a multitude of photographs and diagrams that clearly explain how normal, everyday objects can be misinterpreted as something they're not. The remainder of the book, entitled the Tools Section, covers various techniques that can be employed by the UFO investigator. Everything from animal reactions to radar, hypnosis to lie detectors is explained in full detail. This is the one book that any serious investigator of UFO's should not be without.UFOs versus IFOs: A General Overview.
