In October of 2004, as I am completing editing the articles for this volume, Brewster Kahle of the Internet Archive announced at the Web 2.0 conference that he believes that the twenty-six million volumes in the Library of Congress can be scanned for 260 million dollars and fit into a terabyte of space. As a digital projects coordinator at the Library of Congress, I frankly find this prospect both exciting and frightening (even as I find his math somewhat doubtful).
