Wouldn't it be a nice discovery if it is proven that there are different versions of the Koran out there - thus demonstrating that is is not a divine revelation? Such a discovery would weaken the rigid conservative elements within the Islamic world.
But besides that, all of history is worth preserving whether or not one has distaste for certain elements of a culture.
I certainly hope that it's true that professional smugglers got this stuff out, particularly any untranslated tablets. As long as the stuff is still intact, even if it takes 100 years or more, it can be recovered.
I'm a student of history, which makes it all the more odd that I really don't give a rip about Korans that are destroyed. I guess I'm "intolerant," but I have little tolerance for a false religion that uses the sword as its principal evangelistic tool.
