This one-volume reference work created by professional parapsychologists covers more briefly much of the same material as the classic Encyclopedia of Occultism and Parapsychology , edited by Leslie Shepard ( LJ 5/15/78). Even libraries with that two-volume work will need this one, especially for its updating, large bibliography, and listing of publications and college courses arranged by country. The new work's only real drawback is its lack of a cumulated total index, which the Gale volume contains.
