British National Bibliography vs Urantia Papers

The British National Bibliography is the British Library's record of everything published in the UK and Ireland since 1950, now published as BIBFRAME/RDA linked open data through the multi-national "Share Family" platform. Its original bnb.data.bl.uk endpoint has been offline since the Library's October 2023 cyber-attack destroyed its digital infrastructure; the catalog has since resurfaced on a beta institutional search portal, per the Library's own service-status and metadata-services pages.

Serves the complete 197-paper Urantia Book as structured JSON — by paper, section, or paragraph — with keyword search (AND/OR/phrase modes) and meaning-based semantic search, plus cross-references to Bible passages and AI-narrated audio for every paragraph. It's built for agent/RAG consumption specifically: a `/toc` endpoint enumerates the whole work up front, and `/paragraphs/:ref/context` returns surrounding paragraphs so a single retrieval call carries enough context. Reading and search endpoints are fully keyless; an optional OAuth app-registration flow exists only for personalized bookmarks and reading-progress, not for basic access.
