The series contains many letters and official documents. Letters to the Republic were written by various Ottoman dignitaries, from the grand vizier to local authorities of the towns and places near the Dubrovnik border. Official documents are orders and charters of sultans, orders of the governors of the Ottoman provinces and various documents of kadis. The documents in the series Acta Turcarum provide an excellent insight into all aspects of relations between the Ottoman Empire and the Republic of Dubrovnik, from interstate to personal. The series contains a small number of documents in other languages: Armenian, Arabic and Judeo-Spanish.

The series also contains a small number of documents in Judeo-Spanish, written in Latin alphabet and Hebrew (vol. E17b, E18a, E18b, D, XXIII).
