A small data product packages historical source files with cleaned OCR, table-aware chunks, metadata, grounded Q&A, and retrieval indexes for AI agents.

Landing page captured for the 2026-08-28 issue.

Field notes

The project converts source documents into several retrieval layers: cleaned OCR, table-boundary chunks, metadata, grounded Q&A, embeddings, and an FTS5 index. Its Radio 1926 sample reports 5,219 chunks and 92 QA items, with seed source-recall@3 of 7/8 and QA source-recall@3 of 51/92. The full archive is described as a roughly 52.4MB dated zip rather than a file hosted directly on the landing page.
