Well it's not rare or out of print and the above link is from Amazon and it's the paperback edition I was talking about. It was on page 1 of some of his books and I didn't look at the other two pages.
You can see he's been involved in writing a lot of his own books as well as a consultant/editor to many others.
I saw one new book I think I'd like so I will e-mail him to see if I can get a complimentery copy.
