" LEARNING FROM HYPERTEXT: RESEARCH ISSUES AND FINDINGS "
A computer-based text retrieval system that enables a user to access particular locations in webpages or other electronic documents by clicking on links within specific webpages or documents.
A linkage between related text. By selecting a word in a sentence, information about that word is retrieved if it exists, or the next occurrence of the word is found. For example, in the Windows version of this Encyclopedia, you can hypertext to the definition of any term you encounter by clicking on the word no matter where it is located or by highlighting the word phrase (see virtual hypertext).
Hyperlinks: Hypertext and Hypergraphics
Links embedded within Web pages are addresses to other Web pages either stored on the same Web server or on a Web server anywhere in the world. This "hyperlink" concept is the foundation of the World Wide Web.
Links that display as words are generally underlined to denote them as clickable and are true "hypertext" links. Icons and graphic elements of all sizes and shapes can also serve as clickable links, but are more accurately called "hypergraphics." Thus, hyperlinks are technically either hypertext or hypergraphics. In practice, the terms "hypertext" and "hyperlink" are used the mostly frequently, and often synonymously.
Back to the 1960s
The hypertext concept was originally conceived by Ted Nelson in the mid-1960s as a method for making the computer respond to the way humans think and require information. See hyperlink and virtual hypertext.
