I believe a couple of misconceptions need to be cleared up.
* According to ancient sources Caesar did NOT burn the Library of Alexander. A warehouse of books burned during his taking control of the city.
* the library would NOT have contained unique texts, but rather copies of famous books. Unique copies of someone's work would have stayed with them
and their family... libraries don't accept everything they're offered. It worked much like a modern library with an acquisitions and cataloging
department and was the first library to collect works from outside the country.
* As to the discovery, someone jumped the gun on this one, announcing it as THE Library.
* THE Library was destroyed about 400 AD (some 450 years after Caesar hit Egypt), and most of the ancient historians say a mob of Christians did
it:

What hasn't seemed to be discussed, yet, is that at some point in ancient times the majority of the works of accumulated Human knowledge,
after being located into one location, were subsequently burned as the city was under siege, from an invading Army.
You've gotten a wrong impression, actually.
Rome was a rival for Greece, but it was a point of status in Rome to have a Greek tutor. They would not have destroyed The Library although they may
have looted it. The fire at the Alexandrian wharf was started during the riots, when Caesar's troops were burning the Egyptian naval fleet and the
fire spread to other areas from there.
But The Library was not destroyed. The Roman historian, Strabo, reported working in it some 25 years later.
During times of danger, the books were moved to and from other locations such as the Serapium in Serapis (according to ancient sources.)
Valued books were copied and passed around to royal libraries across the Mediterranean. The collection itself was unique, but there were copies of
these books around...they were the basis of the flourishing of the arts and sciences in Greece (because Alexandria might have been on Egyptian soil
but it was a Greek city) and Rome.
I'll see if I can find some ancient sources for you... a lot of the modern material on this library was made up by people who didn't bother to read
Plutarch and Strabo.
