You’d be hard pressed to find a use for books other than reading. Some people use them as doorstops, others use them to prop up a table leg to cut down on the wobbling.
Others, still, like to use them for bonfires. But that’s another story.
One guy, however, found a way to turn books into an art form. He takes old books and sculpts mountains into them. You’d have to see it to believe it: Mountains of Books Become Mountains.
You could argue that it’s a waste of good books. But if you have to use books for something other than reading, this is a pretty good way to do it.
