Unusually
Sometimes copyright is painfully and incorrectly applied as a money grab. I don't think that's the case here and I'm with the big publishing houses on this one. Libraries will eventually buy more copies of the books as they wear out, and not all books are available in all libraries.
They have to protect their claim and this is a real infringement. You should have to pay while a copyright is held, but I would add that in my opinion copyright should not extend beyond a human lifetime.
