Handbook to UFOs, Crop Circles, and Alien Encounters

"Besides acknowledging the long, wide appeal of these mysterious creatures, places, and events in human history, these "quick reference guides" cover long ago and recent and far and near occurrences. . . .Evenhanded in the matters of belief and believability, the texts include a few hoaxes and always state that there is no scientific evidence proving the existence of any of these paranormal subjects. However, they don't discount the possibilities either. Concluding multiple choice questions test readers' recall of facts. Good overviews for collections that need additional materials on these popular topics."
