Mysteries of the Unknown - Psychic Powers

Mysteries of the Unknown is a series of books about the paranormal, published on the North-American home market by Time-Life Books from 1987 through 1992. Each book focused on a different topic, such as ghosts, UFOs, psychic powers and dreams. Book titles included The UFO Phenomenon, Witches and Witchcraft, Hauntings, and more. According to the LinkedIn page of Tom Corry, Time-Life's then-vice president of product management (1984–90) and under whose auspices the series was launched, it was "the largest selling book series Time-Life ever produced."
