For the Bible anyway, people go back to the most complete and ancient manuscripts to do translation work and to check the textual integrity of translations and copying.
The Sinaitus is the easrliest complete Bible known to exist written on parchment and bounded and covered. and is owned by a Greek Orthodox monastary on the traditionally held mountain of Sinai in Eygpt and a priest orginally from the States is the librarian. He is using a camera that has a resolution of 70 million pixels to capture photos of ancient manuscripts, like Homer from the 1500's and of course, the no le resistanse, the Sianiticus. He then posts these photos on the Internet for all the world to see. I forgot the website, but you could google it.
