This book is an interesting overview of the UFO phenomenon. I recommend this book for people curious about UFOs, who haven't done extensive reading on the subject. It primarily focuses on UFO phenomena in the United States, with a very good section on the U.S. government's official response to UFOs.
Particularly useful is the glossary of terms and institutions in the back of the book. It helped me keep all the various government agencies and projects straight. Bill Yenne does a very good job of presenting the evidence and letting the reader decide for themself. If you are looking for a good book to introduce you to UFO evidence, I recommend you start here.
Take an objective look at the recurring sightings of unidentified flyinc objects and the official investigations and evaluation of those sighting: with UFO. Dozens of case histories are documented, from regiona reports of strange lights and shapes in the sky to firsthand account: of mysterious spacecraft encountered at various places around the world. Ongoing studies by governments, universities, and independen researchers have failed to explain many of the most puzzling cases
