World Wide Web (1934) Wrote numerous essays on how to collect and organize the world’s knowledge. Founding father of documentation, the field of study now more commonly referred to as information science. His vision of a great network of knowledge was centered on documents and included the notions of hyperlinks, search engines, remote access, and social networks.

Hypertext, Wiki, Blog (1946) Bush proposed the notion of blocks of text joined by links and he also introduced the terms links, linkages, trails and web to describe his conception of textuality. A single author connects documents that are associated by some common theme, annotated with commentary and available for others to read long after the original associations are made. Bush goes on to describe the sharing of trails between people and the creation of a ―new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of common record.

Networked Computer with GU Interfaces (1960) Computers should be developed with the goal „to enable men and computers to cooperate in making decisions and controlling complex situations without inflexible dependence on predetermined programs.― He foresaw the need for networked computers with easy user interfaces. His ideas foretold of graphical computing, point-and -click interfaces, digital libraries, e-commerce, online banking, and software that would exist on a network and migrate to wherever it was needed.

―Hypertext‖, Simple User Interface (1965) However, Nelson says he dislikes the World Wide Web, XML and all embedded markup, and regards Berners-Lee's work as a gross over-simplification of his own work: ―HTML is precisely what we were trying to prevent — ever-breaking links, links going outward only, quotes you can't follow to their origins, no version management, no rights management.‖ – Ted Nelson
