-- Vol. 4. "This fourth volume discusses the publishing procedure for secular and religious writings of late antiquity and the factors that led to the impoverishment of the monumental libraries in Rome. New centers of learning grew up in the monasteries, where great libraries containing educational and instructive books and representative works of Christian literature came into being. Monastic libraries were founded throughout Europe, including the regions with Celtic and Anglo-Saxon populations: those at Monte Cassino, Bobbio, St. Gallen, Fulda, Cluny and elsewhere are dealt with extensively. Mention is also made of the libraries founded in universities and of the new philosophy of forming school libraries, as in Bologna and Paris."--Publisher's website.

Vol. 5. "In this fifth volume, the author writes about the re-evaluation of the ancient world: this set in motion a quest for the surviving works of ancient Greek and Latin literature, most of which were to be found in monastic libraries. He discusses the new schools and scholarly circles that were formed to promote the spread of Greek and Latin literature, especially philosophical works, and the emergence from them of the first humanistic libraries. He evokes the character of the libraries belonging to patrons of literature and the arts, such as Matthias Corvinus, the Vatican, the Medici family, the Dukes of Urbino and François I, among many others. Finally, there is an excellent treatise and circumstantial account of the invention of printing, which changed the scene as regards the dissemination of books and the formation of libraries in such a way that the world of books during the Renaissance witnessed a return to the state of affairs existing under the Roman emperors from Augustus to Hadrian."--Publisher's website.
