    Abstract
    'Videotex' was an early incarnation of what have been more recently called 'end-user information services'. This article considers the origins and historical development of videotex over three decades, comparing various nationally sponsored and private systems in Europe and North America, and discussing reasons given for the 'failure' of videotex. The influence of nontechnical factors on videotex and perceptions of critical problems and acceptable solutions are described. According to this interpretation, the development of videotex faced four 'bottlenecks' at once: the determination of transmission channels; the choice of a display device; agreement on coding standards; and the marketing of these resulting services. In how it accomodated these problems, videotex provides an example of how social, political, and economic elements are inseparable from technical constraints in the development of new information technologies

    Abstract
    The article suggests how future models of text storage and retrieval can be informed by research on subject aspects of cognition; future designs may draw upon cognitice theories of categorization and metaphor to understand how users interact with text, both paper and electronic. The results from the study of 20 American historians imply the importance of metaphors for storage and retrieval of documents
