|Copy of Gutenberg Bible in NY Public Library|
Books had been printed on presses before, but Gutenberg used metal type and made a press that could print many versions of the same text quickly.
His contributions to printing were:
- oil-based printing ink,
- reusable metal type,
- a functioning printing press,
- a rapid system for assembling the type into a full book and then folding the pages into folios, which were then bound into an entire volume.
The buying, selling and ownership of Gutenberg Bibles is a topic of its own:
- The General Theological Seminary in Manhattan sold a Gutenberg Bible to make ends meet.
- Will Woodin owned a Gutenberg Bible and there are questions about what happened to it after he died.
