Abstract
As new technologies allow us to change the way we publish information, moving from hardcopy to on-line and the Web, we find that we need to distribute electronic information in a multitude of formats on different platforms concurrently, while exploiting the electronic medium. In addition, we face the challenge of organizing this information on media such as CD-ROM, LAN, and the Web so readers can search through the information successfully. To be able to create, maintain, and update this information, we recommend using a single source of information; to display this complex interactive material in a way that readers can make sense of we recommend adopting a book metaphor.
