Founded in 1976, with membership that consisted of scientists, engineers, technicians, and interested individuals, to investigate and conduct research into unexplained anamolous scientific phenomena of the kind usually associated with Charles Fort. Members are trained in investigative techniques and supply speakers to universities and organizations. The name of the group is the Latin word for "investigate," which, in itself, means footprint.
The group sponsored charitable programs, maintained a library and biographical archives, compiled statistics, and offered computerized services. It had committees on photography and technical matters, and divisions on aerial phenomena, biological matters, earth sciences, and parapsychology, as well as published an annual newsletter. Last known address: 56 Brookwood Rd., Stanhope, NJ 07874.
