The library is housed in a specifically-designed space in the south wing of the new enclosure. Although the bulk of the Monastery's collection was unfortunately lost over the centuries, it still includes about 550 manuscripts, including three parchment liturgical scrolls. The number of music manuscripts is particularly significant. Some of the modern music manuscripts, mainly liturgical services, are not yet known to the general public because they are still unpublished. There are about 15,000 printed books, as well as one of the largest collections of old prints on Mt Athos.
