«Frammenti libreschi» dell’Archivio storico comunale di Sarnano. Un contributo alla storia della Biblioteca

This contribution adds to the knowledge of the manuscript heritage related to the Sarnano Library by presenting a study of the manuscript fragments on parchment and paper preserved in the Sarnano Municipal Historical Archive, which have been reused since the late Middle Ages as covers, endpapers and binding reinforcements for archive and library volumes. Twenty-one examples, dating from the late eleventh to the fifteenth century, are catalogued and analysed using a form that documents both their original production and their subsequent reuse.
