Babel Nexus Index

Explore classic books and big ideas in a whole new way — a discovery system for the public domain. A three-floor knowledge graph: 21 science hexagonal galleries on Level I, 22 literature hexagonal galleries on Level II, and 8 wisdom hexagonal galleries on Level III — 51 hexagonal galleries holding 716 primary works (books, papers, and reports, every one in the public domain), plus 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 knowledge-graph explorer at https://babelnexus.com, built for students tracing an idea back to its source, researchers mapping how disciplines connect, writers hunting for material, and curious readers — every full text is free to read. Each hexagonal gallery is a thematic shelf; hexagonal galleries are connected by typed edges that descend directly from Bush's "associative trails" idea in *As We May Think* (1945). At the exact center of every hexagonal gallery is a spiral staircase to the next floor — Borges' hexagonal-gallery architecture, made navigable. Visitors can walk the graph, ask the Oracle natural-language questions, build and share their own associative trails, and view every primary source's full text via Project Gutenberg, Internet Archive, or Wikipedia.
