Source Library

embassy-of-the-free-mind/sourcelibrary-v2

Connects Claude to the Embassy of the Free Mind's collection of 15,000 rare pre-modern texts, all translated to English. The corpus spans philosophy, religion, science, and literature from before the modern era. Search operations hit the sourcelibrary.org API, which runs on a Next.js stack with MongoDB Atlas for storage and Google Gemini handling OCR and translation of the original manuscripts. Reach for this when you need primary sources from historical periods or want to query obscure philosophical and religious texts that aren't in standard training data. The underlying system processes images through a pipeline that splits two-page spreads, extracts text, translates, and summarizes.

book_idstring

Search within a specific book

diversitystring

Re-order the passages for spread. "author": at most one passage per author and per work in each ten, for a cross-author survey. "tradition": at most 2 per tradition family and per work. Default "of...one of tradition · author · off

exclude_authorsarray

Drop passages by these authors, e.g. ["Agrippa"]. Use it to iterate a survey: run, see who dominates, exclude, run again.

exclude_languagesarray

Exclude these languages, e.g. ["Latin", "French", "German", "English"] to surface non-Western sources.

languagesarray

Filter to any of these languages, e.g. ["Sanskrit", "Arabic", "Chinese"]. Use instead of language when targeting multiple traditions.

limitnumber

max_per_authornumber

Hard cap on passages from one author; the rest are DROPPED (unlike diversity, which only re-orders). Set 1 for "N quotes from N different authors".

max_per_worknumber

Hard cap on passages from one WORK (all printings and editions of it count together, via work_id), so seven printings of De occulta philosophia are one witness, not seven.

offsetnumber

Pagination offset (use with limit to page through total_matches; default 0)

max_per_booknumber

Cap on passages from any single book. Useful when one book dominates the conceptual neighborhood; for one passage per author or per work use max_per_author / max_per_work.

max_per_worknumber

Hard cap on passages from one WORK (all printings and editions of it count together, via work_id), so seven printings of De occulta philosophia are one witness, not seven.
