Bibliothèque Mazarine, Paris
Middle English librarie, from Anglo-Norman librarie, from Old French librairie, from Latin librarium (“bookcase, chest for books”), from librarius (“concerning books”), from liber (“the inner bark of trees, paper, parchment, book”), probably derived from a Proto-Indo-European base *leub(h) (“to strip, to peel”). Displaced native Middle English bochus, bochous (“library, bookhouse”) (from Old English bōchūs (“library, bookhouse”)).
