You think your finger grease does bad things to your smartphone's touchscreen? Just imagine the horrors it would wreak on some ancient documents. As promised , Google has saved history the heartbreak of succumbing to your grubby paws by digitizing the Dead Sea Scrolls. Like pretty much everything else these days, the software giant has added the oldest known biblical manuscript to the cloud. Five scrolls are now available as hi-res images, which really you give the feel of their long-dead animal skin parchment. Google is also offering up English translations of some of the documents and is letting users add comments, because apparently historians weren't too keen on letting people pencil in the margins of the real thing.
