    >> Golly, Doug, I didn't think I had ordered Amazon's last copy. Going to A 
    just now it looks like there are a couple of copies of the paperback I have 
    for $10, and another old-fashioned looking hardback for $100. To find them 
    you have to enter most of the title, Short, easy . . . Just entering Martelli 
    in the search box doesn't cut it.
