1 HYPERTEXT “The origin of the concept of hypertext is normally associated with an article published in 1945 by Vannevar Bush: "As we may think" …, while the term itself was coined by Theodore Nelson in the early sixties, and practical implementations of the concept did not begin to appear till the middle eighties, with the World Wide Web as the popular breakthrough in the nineties.” From “Hypertext concepts: A Historical Perspective”

2 HYPERTEXT “What Vannevar Bush suggested in his conception of the Memex was a principle of document organisation that reflected … the relationship between the documents as perceived by the user, that is the individual scientist, scholar, engineer, lawyer, physician etc. The relationship… ought to be associative rather than systematic… In 1945 … no computer existed that could handle such a job, and Vannevar Bush based his ideas on such technologies as microphotography, tape recorders, teletypewriters, photocells, cathode ray tubes and mechanical calculators… The Memex was strictly a device for individual use - a sort of mechanized private file and library…. The memex … was never built. It was a daring vision but quite impractical with the technology Bush had in mind ” From “Hypertext concepts: A Historical Perspective”

3 HYPERTEXT “Theodore Nelson… in 1972, claims that Vannevar Bush is not describing a new form of "information retrieval", as has often been said, but the principles of Hypertext. In fact, Theodore Nelson points out.. "Bush rejected indexing and discussed instead new forms of interwoven documents." Vannevar Bush talks of "trails" obviously meaning an interlinked set of "documents, documents excerpts, and comments upon them" and "Such non-sequential or complex text structures we may call 'hypertetexts‘...” From “Hypertext concepts: A Historical Perspective”

4 HYPERTEXT “Nelson’s Xanadu expressed a daring vision, equal to the vision of Memex, of storing everything that anybody has ever written, in electronic form, accessible via a computer, and having users create links between them in an associative manner…“ From “Hypertext concepts: A Historical Perspective”

5 HYPERTEXT "Hypertext [is] non-sequential writing. [...] A link is simply a connection between parts of text or other material. It is put in by a human. Links are made by individuals as pathways for the readers‘ exploration; thus they are parts of the actual document, part of the writing. [...] The link facility gives us much more than the attachment of mere odds and ends. It permits fully non-sequential writing, or hypertext. This simple facility -- the jump-link capability -- leads immediately to all sorts of new text forms: for scholarship, for teaching, for fiction, for hyper-poetry. This makes possible a certain free-form serendipitous browsing.“ Ted Nelson: Literary Machines From “Hypertext concepts: A Historical Perspective”
