In 1857, when scholars in the new reading room of the British Museum looked up from their books, they could gaze upon the inspiring vastness of the blue and copper dome above them. By the time it closed, 140 years later, they were cursing the many hours they had to look at the dome while they waited for their books to arrive. A book would seldom arrive within two hours of being ordered, and sometimes readers would have to wait up to two days. This was because, in addition to the museum, the books were stored all over London, and some as far away as a depot in Yorkshire.
