If you google for the Myers-Briggs test, you'll find a simple explanation of what it means to be introverted and extroverted. Introverts are often shy, but not necessarily so. It has more to do with where one finds stimulation. Introverts look internally, extroverts look externally. As such, it's no surprize that heavy readers are often introverts.
