This catalogue examines 122 manuscripts, containing 224 treatises in the disciplines of Qurʾānic sciences, Prophetic tradition, Islamic jurisprudence and its branches, Islamic creed, supplications, etiquettes, admonition, Islamic sufism, logic, syntax, dictionaries, literature, mathematics, astronomy, etc. The catalogue contains many rare works, or ones not found anywhere else in other libraries of Bosnia Herzegovina, such as “Miftāḥ al-fātiḥah” in Arabic, which discusses the qualities, merits, and exegesis of the Noble Qurʾān; the manuscript “Al-Fawāid al-fiqhiyyah fī aṭrāf al-qaḍāyah al-ḥukmiyyah”, which is a study in Arabic based on the Ḥanafi juristic tradition discussing Islamic law rulings related to the work of judges; “Kitāb al-Qaṣb” which is a judicial juristic work, and “Zubdat al-anẓār fī ḥal ‘uqad iẓhār al-asrār”, which is a book on Arabic syntax and morphology (al-naḥw wa al-ṣarf). This manuscript collection has special value due to the fact that it includes many works written by Bosnian authors, in addition to benefiting those wishing to study the Islamic cultural heritage of Bosnia-Herzegovina. One of the highly important Bosnian manuscripts –which can be found in this collection-, is “Al-Fatāwā al-Aḥmadiyyah al-Mostāriyyah”. This is a collection of fatwas in Turkish, authored by Aḥmad b. Muḥammad al-Mostārī. The fatwas in the collection resolve issues and problems encountered daily, and have been consistently referred to by muftis and judges, up until the Austro-Hungarian occupation of Bosnia in 1878. It is worth stating that a large number of these manuscripts were transcribed by Bosnian copyists, who could be found in all parts of the Ottoman Empire.
