[Margaret Pilkington]

If it were my work, I would want to share it.
Allow others who have an interest to access the information. (As Walter has said this information is only of interest to a very small group of people. Which is why his books are not a commercial print proposition)If they wanted to reproducece it then they would have to ask for permission and attribute the information to my research.

Walter has made his decision and that is how he wants it to be.
That has to be respected, whatever any of us think.
