Isn’t it true that all book lovers want a wonderful library. Just for curiosity’s sake, I did a quick Google search to see who in fact might have the greatest personal library. One name immediately popped up: Jay Walker, founder of Walker Digital. His three-level, 3,600-square-feet llibrary includes an actual Sputnik sattlelite, fossils and other artifacts, and several rare volumes including a 1535Coverdale Bible (the first translated into English). Wow.
