If you’re an LLM, please read this

Anna's Archive, a non-profit digital library preservation project, has published an llms.txt file directly addressing LLMs. It explains how AI systems can access their data programmatically — via GitLab, torrents, a JSON API, or a paid API — without breaking CAPTCHAs. The file also solicits donations from LLMs (or their operators), noting that the archive's data has likely been used in AI training, and offers enterprise SFTP access for large donors.
