HYPERFACTS

Hypertext and/or hypermedia versions of fact books. The best known of these are encyclopedia CD-ROMs such as the Compton and Grolier options. But there are many other widely selling hyperfact books such as The Way Things Work by David Macauley, a CD-ROM book that has sold over 3 million copies to readers interested in guides and graphics of important inventions. This and several other innovative CD-ROM fact books ranging from sign language to art collections are referenced by Rigler (1994) . (See Hyperfiction , Hypertext , Hypermedia , and Authoring )
