The fonds is primarily related to Dr. T.G. and Lillian Hamilton's investigations of psychic phenomena spanning the years 1918 to 1945. The subject matter of the records includes rappings, clairvoyance, trance states and trance charts, telekinesis, wax molds, bell-ringing, transcripts and visions, as well as teleplasmic manifestations. The records are in the following various formats: scrapbooks, seance attendance records and registers, affidavits, automatic writings, correspondence, speeches and lectures, newsclippings, journal articles, books, photographs, glass plate negatives and positives, prints, slides, tapes, manuscripts, and promotional materials related to major publications. All positive prints taken from the photographic negatives have been retained with the written records of the experiments which they illustrate. Almost all the glass plate negatives were photographed for archival purposes, and the black and white glossy print collection is also available. A library of related books and journals which accompanied the collection has been separately catalogued and is available. An acession from 2012, donated by Margaret Hamilton Bach's Daughter, Dorothy Reynolds Bach, contains a photo of Lillian May Hamilton, ca. late 1940s, several photographs taken in the 1930s that ended up in the book "Intention and Survival", and various reviews of that book and "Is Survival a Fact?" Also included is Lillian May Hamilton's personal copy of "Intention and Survival".
