The series contains the correspondence between the authorities of the Dubrovnik Republic and Ottoman dignitaries and administrative officials from the neighbourhood of the Dubrovnik Republic in the period from between the 40s and the 70s of the 18th century.

There are very few references to Jews in the series, and the references found provide some insight into the connections between Dubrovnik and Bosnian Jews. For example, several Jewish merchants are listed in the inventories of foreign merchants who transported different goods to Dubrovnik (vol. 1, no. 27, 28). Some Jewish people also appear in several letters that these merchants wrote. For example, a Bosnian Jew, Abram Pardo, wrote to his relatives in Dubrovnik and asked them for financial help because he had recently gotten married (vol. 2, no. 236). Joseph Danon from Travnik, on the other hand, wrote to Raphael Costantini and informed him of the important role of the Bosnian governor in the current Venetian-Dubrovnik conflict (vol. 1, no. 114).
