The Gemstone file was written in many segments over a period of years–by an American man named Bruce Roberts. Parts of the file were released to certain Americans beginning in 1969. The number of handwritten pages is well over a thousand, of which I have read about four hundred. I have been able to verify some of the statements made in the file, but do not have the time or the re- search facilities to verify the entire story. Perhaps others can nelp.
Since the scope of the work is so large, and the events described so complex and interlocking, it may be more easily understood with this skeleton outline of the Gemstone thesis. Individual papers can then be read witn greater comprehension.
