Much of the 1950s was spent fixing the parts of the Museum destroyed by the bombing, and bringing back the pieces that had been taken away. During all this time the collection continued to get bigger, although space was slowly running out for all the books being brought in. The British Library was set up in 1973 to deal with this problem. In 1972 the Museum was loaned the Tutankhamun collection from the Museum of Cairo. They held a big exhibition called 'The Treasures of Tutankhamun' and it attracted over 1.5 million people to come and see it.
