The Magnus Liber or Magnus liber organi (English translation: Great Book of Organum), written in Latin, is a repertory of medieval music known as organum. This collection of organum survives today in three major manuscripts. This repertoire was in use by the Notre-Dame school composers working in Paris around the end of the twelfth and beginning of the thirteenth centuries, though it is well agreed upon by scholars that Leonin contributed a bulk of the organum in the repertoire. This large body of repertoire is known from references to a "magnum volumen" by Johannes de Garlandia and to a "Magnus liber organi de graduali et antiphonario pro servitio divino" by the English music theorist known as Anonymous IV.[1][2] Today it is known only from later manuscripts containing compositions named in Anonymous IV's description. The Magnus Liber is regarded as one of the earliest collections of polyphony.
