Source for movement
The source for movements is a self-published book (iUniverse). In addition I can find no evidence that the author has any qualifications in this field. As a reviewer said, "The author doesn't say whether this is a widely held opinion, or merely his own speculation; and without any biographical information about the author, it's hard to know what's reliable in the book, and what's not." The deliberate lack of footnotes in the book doesn't help. Dougweller (talk) 12:24, 16 October 2013 (UTC)
