<P> Hypertext documents can either be static (prepared and stored in advance) or dynamic (continually changing in response to user input, such as dynamic web pages). Static hypertext can be used to cross-reference collections of data in documents, software applications, or books on CDs . A well - constructed system can also incorporate other user - interface conventions, such as menus and command lines . Links used in a hypertext document usually replace the current piece of hypertext with the destination document . A lesser known feature is StretchText, which expands or contracts the content in place, thereby giving more control to the reader in determining the level of detail of the displayed document . Hypertext can be used to support very complex and dynamic systems of linking and cross-referencing . The most famous implementation of hypertext is the World Wide Web, written in the final months of 1990 and released on the Internet in 1991 . </P> <P> In 1941, Jorge Luis Borges published "The Garden of Forking Paths", a short story that is often considered an inspiration for the concept of hypertext . </P> <P> 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 . </P> <P> 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 hypertext system he theorized, which was named Project Xanadu, but his first and incomplete public release was finished much later, in 1998 . </P>
