In our always-connected, everything-linked world, we sometimes forget that books are the dark matter of the information universe. While we now possess terabytes of data at our fingertips, we have nonetheless drifted further and further away from mankind's most valuable archive of knowledge: the tens of millions of books that have been published since Gutenberg's day.
That's because the modern infosphere is both organized and navigated through hyperlinked pages of digital text, with the most-linked pages rising to the top of Google Inc.'s all-powerful search-results page. This has led us toward some traditional forms of information, such as newspapers and magazines, as well as toward new forms, such as blogs and Wikipedia. But because books have largely been excluded from Google's index -- distant planets of unlinked analog text -- that vast trove of knowledge can't compete with its hyperlinked rivals.
But there is good reason to believe that this strange imbalance will prove to be a momentary blip, and that the blip's moment may be just about over.
