The Library of the Sorbonne, the largest in Christendom, contained 1722 volumes of manuscripts in 1328. Since many of these volumes contained more than one text, the total number of texts involved would have been substantially higher. According to some accounts, libraries in Moorish Spain or Al-Andalus, especially in Cordoba, may have contained far larger numbers of manuscripts.
