One would think several years would go by before the repairs begin. It takes only one week before the Second Law knocks a brick out of the fireplace and breaks the chain on the garage door opener. Books are there when computers fail. But books are like computers. They are subject to the Second Law of Thermodynamics.
Books wear out.
The bindings fail and the covers fall off. The pages become brittle and dissolve into dust. On my shelves I have a dozen books purchased over forty years ago for my college classes. I am not sure they are going to make it into the next century. Libraries are more than centers of information and entertainment.
