The Philobiblon is a collection of essays concerning the acquisition, preservation, and organization of books written by the mediaeval bibliophile Richard de Bury shortly before his death in 1345. Written in Latin, as was the custom of the day, it is separated into twenty chapters, each covering a different topic relating to book collecting. According to one scholar, the Philobiblon is “one of the longest extant medieval texts on the subject of library management.” In it are several innovations such as the practices for circulation control among the students of the college, utilizing at times an open-stack rather than the dominant closed-stack system. Fifteenth century scholars cited it often. Thomas Kempis, the author of the devotional book The Imitation of Christ, borrowed a whole chapter of the Philobiblon for one of his works, and Mathaus Hummel read from it during the opening of the University of Freiburg.
