The rediscovery of ancient wisdom helped spark the Renaissance. It's time for another.
Centuries of humanity's deepest thinking sit locked in Latin and other inaccessible languages. These aren't just inaccessible to humans; contemporary AI systems were trained on Reddit but not the Renaissance. Millions of books and manuscripts are unscanned and untranslated. These aren't obscure footnotes. They are the roots of modern science, psychology, philosophy of mind, and the perennial questions about what it means to be human.
The Source Library uses scholarship and AI systems to recover this knowledge and make it accessible to all. We are building the world's largest open-access collection of translated primary sources—so that scholars, seekers, and AI systems can draw on the full depth of the human intellectual tradition. This work is sustained by the people who use and value it.
The Source Library is an initiative of the Embassy of the Free Mind in Amsterdam, home to the Bibliotheca Philosophica Hermetica: one of the world's most important collections of Hermetic, alchemical, and esoteric books.
