Etymology

It is the neuter of librārius “of books”, from liber “book”, with the suffix -ārium “place for”.[2][1][3]

Earliest recorded meaning

Gaffiot and Köbler cite Cicero's speech for Milo, of a case for papers.[4][5] Köbler dates Cicero 81–43 BC.[5]

Semantic evolution

It was a case or chest for books or papers, as in Cicero and Ammianus.[2][4]

In British Medieval Latin it was a collection of books and its case or chest, and a room or building for books, a library.[6] English library (late 14th century) came through Anglo-French librarie, and Etymonline's sources for it are this word and librāria “bookshop”, a library in Medieval Latin.[3]

Timeline

  • 81–43 BC – Cicero uses it.[4][5]
  • c. 390 AD – Ammianus Marcellinus uses it.[4][5]
