Massive collection of primary source material and rare secondary sources on all kinds of unusual phenomena. The project’s originator, William R. Corliss, a physicist by profession, published his first volume in 1974 and has published nearly a volume a year since that time.
Some of the general subject areas covered by the Sourcebook Project are strange artifacts, weather and geophysical phenomena, biological anomalies, and space mysteries. Some of the specific subject matter includes spook lights, ball lightning, waterspouts, wolf children, Tiahuanaco (Bolivia) ruins, plate tectonics, concretions and geodes, kinks in Saturn’s rings, pendulum phenomena, infrared cirrus clouds, and water-breathing in mammals.
