The Bible is still selling like hotcakes: something like 100 million new Bibles are printed every year. The FIRST printed Bibles, though... that's a different story.
Only 48 of the Bibles that came off Johan Gutenberg's early printing press are known to exist. The long and twisted journey of one copy, known as "Number 45," are told in Margaret Leslie Davis in her book The Lost Gutenberg: The Astounding Story of One Book’s Five-Hundred-Year Odyssey.
The author gives us a sampling of the journey from private collection to UC-Davis lab to vault in Japan.
