Scholars press for printing clues

A Very Defiant Duckling Named Ender spotted a Princeton Weekly Bulletin Piece on a discovery that could prompt a major reassessment in the history of books and bookmaking, two Princeton University researchers have concluded that 15th century German printer Johannes Gutenberg did not, as has been long believed, invent conventional moveable type.

Using sophisticated digital imaging and computer analysis, Paul Needham, librarian of the Scheide Library, a private collection housed in Princeton’s Firestone Library, and Blaise Agüera y Arcas, a 1998 physics graduate, discovered discrepancies between individual letters that they could only explain by concluding Gutenberg used an alternative technology.
