"Reading is to the mind, what exercise is to the body. As by the one, health is preserved, strengthened, and invigorated: by the other, virtue (which is the health of the mind) is kept alive, cherished, and confirmed." Joseph Addison
The largest bound book in the world is The Klencke Atlas. A 1.75 meter tall by 1.9 meter wide tome that is so heavy six people are necessary to lift it. It was presented as a gift to Charles II of England by Johannes Klencke in 1660. The atlas contains 37 printed wall maps.
