Traveling Library

Abdul Kassem Ismael, the grand vizier of Persia, was an avid reader with a library of about 117,000 books. But Ismael, a frequent traveler, hated the idea of separation from his beloved collection, so he took it with him, using more than 400 camels to transport the literary works. To ensure that the needed book could be quickly found, the camels were trained to travel in alphabetical order.
