Kuma,
i think if you look closer on Amazon, you will see that the book is out of print.
so anyone selling it is selling a used copy or a new one that they have been sitting on.
so they can ask whatever price they like.
whether or not they ever change hands at these prices is another question.
but the high 'asking' prices indicate the supply and demand for that particular volume.
which would appear to be darn few books and at least some demand.
sorry i don't have that book in my 'library'.
but i am surprised none of these 'tread guys' have seen it.
they are notorious researchers.
