In 1953, the museum celebrated its bicentenary.
Many changes followed: the first full-time in-house designer and publications officer were appointed in 1964, the Friends organisation was set up in 1968, an Education Service established in 1970 and publishing house in 1973.
In 1963, a new Act of Parliament introduced administrative reforms.
It became easier to lend objects, the constitution of the board of trustees changed and the Natural History Museum became fully independent.
By 1959 the Coins and Medals office suite, completely destroyed during the war, was rebuilt and re-opened, attention turned towards the gallery work with new tastes in design leading to the remodelling of Robert Smirke's Classical and Near Eastern galleries.
In 1962 the Duveen Gallery was finally restored and the Parthenon Sculptures were moved back into it, once again at the heart of the museum.

By the 1970s the museum was again expanding.
More services for the public were introduced; visitor numbers soared, with the temporary exhibition "Treasures of Tutankhamun" in 1972, attracting 1,694,117 visitors, the most successful in British history.
In the same year the Act of Parliament establishing the British Library was passed, separating the collection of manuscripts and printed books from the British Museum.
This left the museum with antiquities; coins, medals and paper money; prints & drawings; and ethnography.
A pressing problem was finding space for additions to the library which now required an extra 1 ¹⁄₄ miles (2.0 km) of shelving each year.
The Government suggested a site at St Pancras for the new British Library but the books did not leave the museum until 1997.
