The “Faire savoir” collection, launched in 2021, features works based on research conducted in various forms at the Collège de France. It aims to contribute to “conveying knowledge as it is being created,” in keeping with the institution’s guiding principle, regardless of the discipline or subject addressed. Some books are the culmination of extremely recent, entirely unpublished work, while others are based on older studies—also unpublished—whose records are preserved in the archives of the Collège de France.
