A review of the Macintosh CD-ROM versions of The Manhole, the Time Table of History, and the Electronic Whole Earth Catalog with emphasis on their usability and their support of hypertext navigation. Based on the discussion of these hypertexts the following general principles are found to be useful for analyzing hypertext user interfaces: Navigational dimensions and their explicitness, directionality and literalness, landmarks, locational orientation, history lists, and backtrack mechanisms.
