Forty-eight Gutenberg Bibles still exist, although only 21 are complete, and many of them can be viewed online. The University of Texas at Austin copy can be seen here. (Click on “Turn the Pages.”) The Library of Congress’s Gutenberg Bible can be viewed here. The British Library has two copies of the Gutenberg Bible, one printed on paper and one printed on vellum, and they can be viewed and compared here. Click on “Texts.” If you compare the British Library’s two copies, be sure to notice that the black type is identical on the two copies, but the colored decorations are different.
