The series contains records of maritime insurance for merchandise that mainly arrived from the area of the Ottoman Empire and was primarily transported to Italian ports (mostly Ancona and Venice). The records contain the following data: the name of the sales representative, the name of the merchant, i.e., the owner of the merchandise, sometimes the name of the city where the merchant lived, details of the merchandise (type and quantity), place of loading, name of ship, name of captain, place of unloading, name of insurer and price insurance. The records of the series are from the middle of the 16th century to the middle of the 18th century.

Between 1564 and 1646, the record shows that approximately 4,000 maritime insurance contracts were registered with references to Jewish population. The series is, therefore, very important for the research of business affairs of Jews and for reconstructing their business network in the Balkans and the Mediterranean. Jews appear in this series both as merchants and as trade representatives. It is also apparent that Jewish merchants who sent their goods through Dubrovnik, would choose, almost always, Jewish trade representatives. Most of these sales representatives, who were in charge of securing the goods and of shipping these from Dubrovnik, were members of Jewish families such as Abeatar, Abendana, Abenun, Azubi, Benmelech, Cabiglio, Coen, Cusi, Danon, Ergas, Maestro and Oef. Among them, Samuel Ergas, the consul of the Ragusan Jews, Aron Coen, a famous Dubrovnik rabbi, and David Coen de Herrera, the father of Abraham Coen de Herrera (vol. 49, ff. 92, 92v) stand out as famous sephardim of that period. Jewish merchants came from Ottoman cities such as Sofia, Vlora, Sarajevo, Belgrade, Skopje, Bitola. The goods that were sent via Dubrovnik to Italian ports (Ancona and Venice), were usually wool, wax, various types of leather, raw silk and spices. The significance of this series for the history of the Sephardim, can be better understood taking into consideration a doctoral thesis written by Benedetto Ligorio Le reti economiche e sociali degli ebrei nella Repubblica di Ragusa e la diaspora commerciale sefardita, 1546-1667 (Roma, Sapienza, 2017).
