The Society for the Investigation of the Unexplained published its findings on investigations into the anomalous in its unscheduled quarterly, Pursuit Journal (of the Society of the Unexplained). Their research board included at least a dozen, noted scientists of various fields. The Pursuit Journal only lasted a few years. Sanderson died in 1973, and the organization originally disbanded in the 1980s. A Society for the Investigation of the Unexplained apparently exists in Baltimore, but its statement of purpose is quite different, and may not be connected to Sanderson's.
Ivan Sanderson published numerous books and articles under two different names regarding a diverse number of subjects, and was considered skeptical of the paranormal. One researcher posted that a cache of SITU materials had been discovered, but little information has since come to light. Ivan Sanderson coined the term "cryptozoology."
