Babel Nexus Index — A Discovery System for the Public Domain
A knowledge-graph explorer of the public domain. A three-floor Index: 19 science chambers on Level I, 16 literature chambers on Level II, and 8 wisdom chambers on Level III (each floor reached via the spiral staircase at the center of every room), holding 563 primary works (books, papers, and reports, every one in the public domain), and an AI Oracle (powered by Google Gemini) that answers free-form questions about the Archive. Built in the lineage of Jorge Luis Borges' Library of Babel, Vannevar Bush's Memex, and H. G. Wells' World Brain.
The Index is a discovery system: a navigable knowledge graph of the public domain, built on two floors. Each chamber is a thematic shelf holding canonical primary works whose copyright has expired or that were released into the public domain. Chambers are connected by typed edges that descend directly from Vannevar Bush's "associative trails" idea in As We May Think (1945). At the exact center of every chamber is a spiral staircase to the next floor — Borges' hexagonal-gallery architecture, made navigable. Visitors can walk the graph chamber by chamber, ask the Oracle natural-language questions about the Archive, build and share their own associative trails (Bush's idea, made concrete), and view every primary source's full text via Project Gutenberg, Internet Archive, or Wikipedia.
The Oracle is powered by Google Gemini through a small first-party API. The browser bundle never sees the API key.
Knowledge Itself — Bacon's Novum Organum, Locke, d'Alembert's Encyclopédie preface, Dewey, Peirce, Wells's World Brain (the meta-epistemology shelf, and the bridge to Level II)

Lineage
The Index is named for Borges' Library of Babel (1941), built on the architecture Bush sketched in As We May Think (1945), and aimed at the goal Wells named in World Brain (1936–38): a permanent, universally accessible synthesis of human knowledge. It is the latest answer to a question that recurs every few generations — Bacon's Novum Organum, d'Alembert's preface to the Encyclopédie, Dewey's classification, Peirce's semiotics, Ted Nelson's Xanadu, Tim Berners-Lee's Web — what would it look like to make knowledge itself navigable?
