What truth was accidentally discovered in the Vatican's Library?
Ancient Vatican library to close
One of the world's oldest libraries, at the Vatican, is to close for three years for rebuilding, in an unexpected blow to scholars around the world.
The decision to shut the library was made without warning.
After the library closes for its summer break in mid-July, it will not reopen until September 2010, the Vatican says.
The reason is that some buildings constructed only a quarter of a century ago are now considered unsuitable for the safe storage of ancient books.
