Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access, or where text can be revealed progressively at multiple levels of detail (also called StretchText). Hyper
'Hypertext' is a recent coinage. 'Hyper-' is used in the mathematical sense of extension and generality (as in 'hyperspace,' 'hypercube') rather than the medical sense of 'excessive' ('hyperactivity'). There is no implication about size— a hypertext could contain only 500 words or so. 'Hyper-' refers to structure and not size.— Theodor H. Nelson, Brief Words on the Hypertext, 23 January 1967
The English prefix hyper- comes from the Greek prefix "ὑπερ-" and means "over" or "beyond"; it has a common origin with the prefix "super-" which comes from Latin. It signifies the overcoming of the previous linear constraints of written text.
By now the word "hypertext" has become generally accepted for branching and responding text, but the corresponding word "hypermedia", meaning complexes of branching and responding graphics, movies and sound – as well as text – is much less used. Instead they use the strange term "interactive multimedia": this is four syllables longer, and does not express the idea of extending hypertext.— Nelson, Literary Machines, 1992
Types and uses of hypertext
In 1945, Vannevar Bush wrote an article in The Atlantic Monthly called "As We May Think", about a futuristic proto-hypertext device he called a Memex. A Memex would hypothetically store - and record - content on reels of microfilm, using electric photocells to read coded symbols recorded next to individual microfilm frames while the reels spun at high speed, stopping on command. The coded symbols would enable the Memex to index, search, and link content to create and follow associative trails. Because the Memex was never implemented and could only link content in a relatively crude fashion — by creating chains of entire microfilm frames — the Memex is now regarded only as a proto-hypertext device, but it is fundamental to the history of hypertext because it directly inspired the invention of hypertext by Ted Nelson and Douglas Engelbart.
In 1963, Ted Nelson coined the terms 'hypertext' and 'hypermedia' as part of a model he developed for creating and using linked content (first published reference 1965). He later worked with Andries van Dam to develop the Hypertext Editing System (text editing) in 1967 at Brown University. By 1976, its successor FRESS was used in a poetry class in which students could browse a hyperlinked set of poems and discussion by experts, faculty and other students, in what was arguably the world’s first online scholarly community which van Dam says "foreshadowed wikis, blogs and communal documents of all kinds". Ted Nelson said in the 1960s that he began implementation of a hyper
Douglas Engelbart independently began working on his NLS system in 1962 at Stanford Research Institute, although delays in obtaining funding, personnel, and equipment meant that its key features were not completed until 1968. In December of that year, Engelbart demonstrated a 'hypertext' (meaning editing) interface to the public for the first time, in what has come to be known as "The Mother of All Demos".
The first hypermedia application is generally considered to be the Aspen Movie Map, implemented in 1978. The Movie Map allowed users to arbitrarily choose which way they wished to drive in a virtual cityscape, in two seasons (from actual photographs) as well as 3-D polygons.
In 1980, Tim Berners-Lee created ENQUIRE, an early hyper
In 1980 Roberto Busa, an Italian Jesuit priest and one of the pioneers in the usage of computers for linguistic and literary analysis, published the Index Thomisticus, as a tool for performing text searches within the massive corpus of Aquinas's works. Sponsored by the founder of IBM, Thomas J. Watson, the project lasted about 30 years (1949-1980), and eventually produced the 56 printed volumes of the Index Thomisticus the first important hypertext[verification needed] work about Saint Thomas Aquinas books and of a few related authors.
In 1983, Ben Shneiderman at the University of Maryland Human - Computer Interaction Lab led a group that developed the HyperTies system that was commercialized by Cognetics Corporation. Hyperties was used to create the July 1988 issue of the Communications of the ACM as a hyper
In August 1987, Apple Computer released HyperCard for the Macintosh line at the MacWorld convention. Its impact, combined with interest in Peter J. Brown's GUIDE (marketed by OWL and released earlier that year) and Brown University's Intermedia, led to broad interest in and enthusiasm for hypertext, hypermedia, databases, and new media in general. The first ACM Hyper
Meanwhile, Nelson (who had been working on and advocating his Xanadu system for over two decades) convinced Autodesk to invest in his revolutionary ideas. The project continued at Autodesk for four years, but no product was released.

Text provides a single user-interface to many large classes of stored information, such as reports, notes, data-bases, computer documentation and on-line systems help.

One of the most successful computer games, Myst, was first written in Hypercard. The game was constructed as a series of Ages, each Age consisting of a separate Hypercard stack. The full stack of the game consists of over 2500 cards. In some ways Myst redefined interactive fiction, using puzzles and exploration as a replacement for hypertextual narrative.

Forms of hypertext
There are various forms of hypertext, each of which are structured differently. Below are four of the existing forms of hypertext:
- Axial hypertexts are the most simple in structure. They are situated along an axis in a linear style. These hypertexts have a straight path from beginning to end and are fairly easy for the reader to follow. An example of an axial hyper
text is The Virtual Disappearance of Miriam.
- Arborescent hypertexts are more complex than the axial form. They have a branching structure which resembles a tree. These hypertexts have one beginning but many possible endings. The ending that the reader finishes on depends on their decisions whilst reading the text. This is much like gamebook novels that allow readers to choose their own ending.
- Networked hypertexts are more complex still than the two previous forms of hypertext. They consist of an interconnected system of nodes with no dominant axis of orientation. Unlike the arborescent form, networked hypertexts do not have any designated beginning or any designated endings. An example of a networked hyper
text is Shelley Jackson's Patchwork Girl.
- Layered hyper
>text consist of two layers of linked pages. Each layer is doubly linked sequentially and a page in the top layer is doubly linked with a corresponding page in the bottom layer. The top layer contains plain text, the bottom multimedia layer provides photos, sounds and video. In the Dutch historical novel De man met de hoed designed as layered hyper text in 2006 by Eisjen Schaaf, Pauline van de Ven en Paul Vitányi, the structure is proposed to enhance the atmosphere of the time, to enrich the text with research and family archive material and to enable readers to insert memories of their own while preserving tension and storyline.
