The new Bibliotecha Alexandrina, opened in 2002, is an extraordinary cultural and scientific institution. It is a revival of the old library at Alexandria, more than 2300 years old, that was tragically destroyed in the seventh century. Tens of thousands of volumes were then lost, including many astronomical papers.
