BoingBoing reader Larry Carlson says,

The University of Miami has an exhibit of The Jackie Gleason Collection of Books. It includes approximately 1,700 volumes of books, journals, pamphlets, and publications in the field of parapsychology. The collection offers materials on such topics as: witchcraft, folklore, extrasensory perception (ESP), unidentified flying objects (UFOs), reincarnation, mysticism, spiritualism, mental telepathy, the occult, ghosts, clairvoyance, cosmology, demons, hypnosis, life after death, mediums, psychical research, voodooism, and others.

Dude, *yes*, that Jackie Gleason. From the exhibit description:

Gleason, a comedian, television star, and motion picture actor of international acclaim, developed a deep and abiding interest in parapsychology and its many components. Gleason's interest grew from his inquisitive mind and sincere interest in the topic. However, the collection is not the product of Gleason's personal belief in the wide spectrum of phenomena represented by the term "parapsychology."
