Publications prior to 1993 (Ralph Rowbotham, Brian Harney, others)
Many of the briefings issued in earlier days are of course now lost.
Existing versions for scanning would be most welcome.

I had most of 2004-6 archived; thanks to Henry Marston I have missing ones and 2000-3 also.
I have all paper issues 1993-2000 which I may scan in future.
