@OmSigDAVID,
Here is a brief comment from Wikipedia on the library history David and as I said it is never all that simple.
I would suggest you read a few books instead of getting your knowledge from watching old movies<LOL>

However, this version of events is not confirmed in contemporary accounts of Caesar's visit. In fact, it has been reasonably established that segments of its collection were partially destroyed on several occasions before and after the first century BC. A modern myth (no older than the late eighteenth century) attributes the destruction to Coptic Christian Archbishop Theophilus of Alexandria in 391, who called for the destruction of the Serapeum; but in fact there was no connection between the library and the Serapeum and some historians of late antiquity do not take the claim seriously. Another version of the story, not recorded till the thirteenth century, blames the Muslim sacking of Alexandria in 642.[1][citation needed]
Intended both as a commemoration and an emulation of the original, the Bibliotheca Alexandrina was inaugurated in 2002 near the site of the old library.[2]
