The Encyclopedia of the Paranormal contains over 90 articles by more than 50 experts on topics including the strictly paranormal (psychokinesis, channeling, levitation, astrology, phrenology, palmistry); the historical (mediums, psychic research, alchemy, Houdini); the philosophical (miracles, survival of death, reincarnation); and work on investigatory photography, statistics, the media and the Bermuda Triangle.

In his foreword, Carl Sagan says, "I wish [this book] were on the shelves of every newspaper editorial desk and every television newsroom, to encourage more skeptical backbone in reporting . . . . [I]n school libraries so that children would have some counterbalance to the many paranormal and mystical claims in our society."
