isnt there a logical twist in all this.. The problem is that there are so many _different_ books. I have a house not exactly filled, but certainly loaded with books. So people certainly buy books. But of each book, I seldomly have more than one or two. It's a bit like random numbers filling the interval 0-1. each number has 0 probability, but they fill out the infinite space 0-1 fully. But how horrible it would be to only have the 10 best selling books. The bible, anyone..
