# Babel Nexus Index

> A discovery system for the public domain. A two-level knowledge graph: 18 science chambers on Level I and 11 literature chambers on Level II, holding 318 primary works (books, papers, and reports drawn entirely from 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. Each chamber is a thematic shelf; chambers 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 chamber 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.

## Core concepts

- [As We May Think (1945)](https://en.wikipedia.org/wiki/As_We_May_Think): Vannevar Bush's essay proposing the Memex and "associative trails" — the direct ancestor of the Index's edge architecture and Trail Builder.
- [The Library of Babel (1941)](https://en.wikipedia.org/wiki/The_Library_of_Babel): Jorge Luis Borges' fictional infinite library of hexagonal galleries, the namesake and visual inspiration for the chambers.
- [World Brain (1936–38)](https://en.wikipedia.org/wiki/World_Brain): H. G. Wells' proposal for a permanent, universally accessible synthesis of human knowledge — the long arc the Index belongs to.

Plus the hidden 18th chamber, **The Crimson Hexagon**, which unlocks after visiting seven chambers — a Borges easter egg.

## Level II — Literature (11 chambers)

Beneath the sciences sits the literary substrate from which formal knowledge later crystallized. Reach Level II via the spiral staircase at the center of any Level I chamber, or via the dashboard tile.

Cross-level edges connect Wisdom Literature ↔ Knowledge Itself and Philosophy of Science; First Novels and First Plays ↔ Psychology; Epics ↔ Knowledge Itself; Fiction Set in Libraries ↔ Knowledge Itself.

## How the Oracle works

1. The visitor asks a free-form question in the Index UI.
2. The frontend POSTs the question + a snapshot of the Archive metadata to the project's own API server (`/api/oracle/ask`, `/api/oracle/descriptive-index`, `/api/oracle/vindication`).
3. The API server attaches a system prompt and calls Google Gemini's REST API. The Gemini API key lives only on the server; the browser bundle never sees it.
4. Gemini's text answer is returned and rendered. On any failure (no key, API error, offline) the UI falls back to a hand-written passage so the page never collapses.

## Routes

- `/` — Visual Explorer (default chamber)
- `/n/<chamber-id>` — Visual Explorer focused on a specific chamber (deep-linkable, shareable). Valid IDs include all Level I science chambers and the Level II ids: `epics`, `first_novels`, `wisdom_literature`, `first_plays`, `first_mystery`, `first_scifi`, `library_fiction`, `romance_novels`, `first_horror`, `first_fantasy_literature`, `wordless_novels`.
- `/dashboard` — Dashboard overview
- `/archive` — Knowledge Base (master booklist of every work across both levels)
- `/intelligence` — Oracle interface
- `/t/<encoded>` — A walkable associative trail (Bush's idea, made concrete)

## Why it exists

The public domain is the largest open knowledge corpus humanity has ever assembled, but it is mostly invisible — scattered across Project Gutenberg, Internet Archive, HathiTrust, Wikisource, and a long tail of university repositories. The Index is one answer to the question Bush, Wells, and Borges all asked in different ways: *what would it look like to make knowledge itself navigable?*
