The Love of Books: The Philobiblion of Richard de Bury

According to Wikipedia: "Richard de Bury (24 January 1287 - 14 April 1345), also known as Richard Aungerville (or Aungervyle), was an English writer, bibliophile, Benedictine monk and bishop. He was a patron of learning, and one of the first English collectors of books. He is chiefly remembered for his Philobiblon, written to inculcate in the clergy the pursuit of learning and the love of books. The "Philobiblon" is considered the earliest books to discuss librarianship in-depth."
