The Organ Historical Society has a catalog at http://www.ohscatalog.org/
Many books and CD's are available there, including Audsley's two volume
classic, "The Art of Organ Building." Perhaps the guidelines mentioned
are available there.  If not, a call to the Society at 804.353.9226
might provide the answer.
