Though Gutenberg's invention made possible our modern world with all its wonders and woes, no one, much less Gutenberg himself, could have foreseen that his press would have this effect. And no one today can foresee except in broad and sketchy outline the far greater impact that digitization will have on our own future. With the earth trembling beneath them, it is no wonder that publishers with one foot in the crumbling past and the other seeking solid ground in an uncertain future hesitate to seize the opportunity that digitization offers them to restore, expand, and promote their backlists to a decentralized, worldwide marketplace. New technologies, however, do not await permission. They are, to use Schumpeter's overused term, disruptive, as nonnegotiable as earthquakes.
