Via BoingBoing, the Library at Alexandria has been uncovered! This is really exciting, although I doubt any of the missing books will be uncovered. I heard once that the Alexandrians would confiscate any books from visitors to the city to make copies of them for their own library. Piracy has a storied history! The Library at Alexandria was one of the earliest attempts to compile the complete knowledge and science of mankind.
Carl Sagan had good section about it in his book, Cosmos. I found that complete passage here.
