The New York Times Book (sic) Review for March 6, 1994 ran a feature piece reviewing a CD-ROM. "Microsoft Art Gallery," an interactive digitized catalog of Britain's National Gallery collection, won a rave. Just point and click, and you can pull up paintings by artist, period, or genre; you can also get spoken critical commentaries and painter biographies; you can zoom in or print out, all for $79.95. The Times's treatment of a CD-ROM as a virtual book has to be a kind of cultural watershed. The information revolution, decades after predictions of its imminence, has finally reached a popular critical mass.
