Knowledge has never been linear. Every idea connects to dozens of others, forming a vast web of meaning that resists the constraints of sequential presentation. The Xanadu project envisions a world where these connections are made visible -- where every document links bidirectionally, where context is never lost, and where the path you take through information is as meaningful as the information itself.
This wiki traces the intellectual lineage of hypertext from its earliest conceptions to its modern implementations. It maps the relationships between ideas, people, and documents that together form the foundation of our networked age. Each node you encounter here is one point in a constellation that extends far beyond what any single page can contain.
What you will find is not a hierarchy but a web. Not an index but a conversation between texts that span decades and disciplines. The structure itself is the argument: knowledge is relational.
A manifesto for personal computing and the democratization of information. Nelson argues that computers should serve as tools for creative expression, not instruments of institutional control.
The foundational essay that imagined the Memex -- a device for storing and retrieving linked documents. Bush foresaw the associative nature of human thought reflected in machine architecture.
Nelson's comprehensive vision for Project Xanadu: a universal hypertext system with transclusion, bidirectional links, and micropayments for authors. The blueprint for a different internet.
Engelbart's framework for using computers to augment human capability. He proposed collaborative editing, shared workspaces, and dynamic views of structured information.
The paper where Nelson coined the term "hypertext." He proposed a system where every document could reference any other, creating a non-sequential network of textual relationships.
Otlet's Mundaneum envisioned a universal bibliography linking all human knowledge. His card-based system prefigured hypertext by decades, proposing relational indices and cross-references.
The dream of Xanadu was never merely technical. It was a philosophical argument about the nature of knowledge itself: that ideas exist not in isolation but in perpetual conversation, that every text carries within it the traces of every text it has encountered, and that the proper medium for human thought is not the page but the network. The web we built fell short of this vision -- its links are one-directional, its documents are mutable without record, and its structure encourages silos rather than bridges. But the vision persists, encoded in every attempt to link, to cite, to annotate, to connect.
This wiki exists as a small instantiation of that larger dream. It does not claim completeness. It does not impose a single reading path. It offers instead a collection of nodes and the threads between them, trusting that you will find your own way through the network. Every path is valid. Every connection reveals something new about the shape of knowledge. The structure is the content. The map is the territory.
