There are approximately 2,000 manuscripts, handwritten in Syriac, Arabic, Latin, and Greek. They cover a wide variety of topics, such as theology (including many liturgical Maronite texts), Islam, philosophy, Syriac and Arabic grammar, literature, astronomy, and history.
This collection also provides valuable pieces of information about Lebanese heritage and historiography; many of these Maronite manuscripts contain unique remarks recorded by Lebanese manuscripts copyists, which convey rare historical and local events.
