The account
Clark, a long-time editor in the field, wrote detailed, sourced entries that treat both proponent and skeptical views, and the encyclopedia is still a standard reference for researchers.
The sceptical view
Clark is himself sympathetic to the reality of an unexplained phenomenon, and skeptics regard some entries as leaning that way.
