Lalwende -
What a bargain! Lucky Davem and you! I have that book and I definitely didn't pay 115 pounds, but I did pay more than $5.45.
I am threatening to sit down this summer and actually inventory my collection. It would be nice to do a gorgeous website, but I'll be happy with a plain old list so I can remember exactly what I have and what I'd still like to find.
I have frequented a lot of garage and library book sales over the years and have sometimes turned up some good stuff. Anyways I think hunting for books can be as much fun as finding them. Plus, you might start looking for one book on a particular subject and end up finding something else you really love.
Hookbill - sounds as if you've made a great start.
