Hypertext in Context
Cambridge University Press, Jan 31, 1991 - Computers - 166 pages
Hypertext is the term coined for the storage of electronic data, whether it be textual or graphic, in such a way that the whole file, in addition to, say, a word processor, becomes an electronic "concordance." This book positions hypertext in an interdisciplinary area created by the overlap of psychology, computer science and information science, in addition to assessing its importance in the field of electronic publishing. Rather than simply summarize everything that has gone before, it aims to provide a position statement from which further work can be suggested. This book will be of interest to researchers, software authors, publishers and anyone concerned with distributing information.
