William R. Corliss (August 28, 1926 – July 8, 2011) was a cataloger of scientific anomalies (observations and facts that challenge prevailing scientific paradigms) and he published many works on the subject. He wrote 13 books for the National Aeronautics and Space Administration (NASA), a dozen educational booklets for the Atomic Energy Commission (AEC), and a dozen articles for the National Science Foundation (NSF).  According the the Baltimore Sun, "As a physicist, he was Director of Advanced Programs in the Nuclear Division at Martins in the 1960's. Later, he became a prolific writer, authoring 57 books on atomic energy, space propulsion, scientific satellites, teleoperators, wind tunnels, and scientific anomalies in all fields of science."
Corliss obtained degrees in physics from Rensselaer Polytechnic Institute (B.S., 1950) and the University of Colorado (M.S., 1953). Corliss was also a member of the American Association for the Advancement of Science and the Society for Scientific Exploration. He lives in Glen Arm, Maryland, USA, where the Sourcebook Project is located. 
Since 1976, Corliss has published Science Frontiers, a bimonthly newsletter providing digests of reports that cite and describe scientific anomalies.
Concerning the evolutionary and old earth creationism paradigms which theorize the earth is billions of years old, Corliss's work on geological anomalies catalogs scores of anomalies which challenge the old-earth paradigm.
William Corliss wrote the following regarding paraconformities:
|“||Potentially more important to geological thinking are those unconformities that signal large chunks of geological history are missing, even though the strata on either side of the unconformity are perfectly parallel and show no evidence of erosion. Did millions of years fly by with no discernible effect? A possible though controversial inference is that our geological clocks and stratigraphic concepts need working on.||”|
The science magazine New Scientist had an article which focused on the career of William Corliss. New Scientist wrote regarding Corliss's work: "All I can say to Corliss is carry on cataloging".  Arthur C. Clarke described Corliss as "Fort's latter-day - and much more scientific - successor."
