At the time of his death, Moore's collection of books and papers contained over 30,000 items, and may have been the largest in England. To celebrate his coronation, King George I caused it to be purchased intact and donated to Cambridge University. Moore's library alone contained nearly twice the material in the existing University library. While some material has been removed over the years, the gift is still largely intact, and is called The Royal Library in honor of its patron.
