# Blockchain Lab > Desk readings of public design papers. An upstream file is mirrored only when a licence is recorded. Blockchain Lab does not train a model on this library. Desk wording is not a training grant. A mirrored file keeps the upstream licence. Follow that licence, not this note, for the file itself. ## Read - Catalogue (JSON): https://blockchainlab.com/api/v1/studies - One study (JSON): https://blockchainlab.com/api/v1/studies/{slug} - Study page: https://blockchainlab.com/whitepaper/{slug} - Upstream text, only when mirrored: https://blockchainlab.com/primary/{slug}.md - Reading-list builder: https://blockchainlab.com/whitepaper/builder?d={slug},{slug} - Rights: https://blockchainlab.com/research/rights-and-licensing ## What is mirrored (2026-10-10) - 1021 files. 950 are CC0-1.0 from ethereum/EIPs or ethereum/ERCs. - 71 are BIP files whose own text states a licence. The notice stays in the file. - Papers whose source is a docs site, a PDF, or a repository without a recorded licence are not copied. Use source_url on the study. - The builder lists documents and repositories. It does not fork, audit, or deploy them.
