Society for Interdisciplinary Studies (SIS) (L)
The Society for Interdisciplinary Studies (SIS) was founded in 1975 and is “the oldest and most up-to-date Society for information and research into cosmic catastrophes and ancient chronology revision.”
Trevor Palmer who was Chairman of the SIS from 1995-1998 and 2000-2002 has written Perilous Planet Earth, which is a comprehensive history of catastrophism and includes a couple of chapters on Atlantis.
A search on their website(a) reveals a number of articles and reviews relating to Atlantis – not all positive. Their Catastrophism CD(b), although expensive, is an absolute must for any serious student of the subject.
