First of all, I doubt every item was photographed. Second, working from a photograph of a tablet is not nearly as good as working from the tablet. With a photograph, you are limited to detecting cuneiform impressions from the way the light of the camera hits the tablet. Working with the actual tablet allows one to turn the tablet in different ways to get details. It's just not the same. I hope this story is wrong.
No doubt that's true at the research level. For the rest of us, the most we will ever see is a photo and read an analysis. Almost makes you wonder if the bad guys didn't set up this huge (and irresponsible) loss just to blame us, doesn't it?
