The Parapsychology Laboratory records span the years 1919-1984, with the exception of an 1893 letter written by Richard Hodgson, Secretary of the American Society for Psychical Research, to William James. Included are personal papers of J. B. Rhine, J. G. Pratt, L. E. Rhine and other Laboratory staff, as well as professional correspondence, research records, legal and financial papers, clippings, and photographs. Over half the collection is represented by correspondence, and about a third of it by research files. Included are editorial files (1942-1959) of Dorothy Pope, Managing Editor of the Journal of Parapsychology, and papers (1957-1963) relating to the tenures of Rhea White and J. G. Pratt as officers of the Parapsychological Association.
