So... How did they digitise it if they couldn't open it? X-rays? Article completely fails to answer its own title's mystique. Edit: From the original article at Cambridge (http://www.lib.cam.ac.uk/news/oracle-bones-and-unseen-beauty-wonders-priceless-chinese-collection-now-online http://www.lib.cam.ac.uk/news/oracle-bones-and-unseen-beauty...): "Charles Aylmer, Head of the Chinese Department at Cambridge University Library, said: “This is the earliest and finest example of multi-colour printing anywhere in the world, comprising 138 paintings and sketches with associated texts by fifty different artists and calligraphers. Although reprinted many times, complete sets of early editions in the original binding are extremely rare. “The binding is so fragile, and the manual so delicate, that until it was digitized, we have never been able to let anyone look through it or study it – despite its undoubted importance to scholars.” " So not too fragile to open, just too fragile to allow everybody who would like to to open it.
