The subseries contains correspondence between the authorities of the Republic and its diplomatic and consular representatives in Vienna, St. Petersburg, several Italian cities such as Rome and Venice, and in some North African cities. The subseries also includes correspondence between state authorities and local authorities in the Republic, as well as the correspondence between Republic authorities and Austrian, Russian and French consuls in Dubrovnik. Most letters sent by the Dubrovnik authorities to the fore-mentioned addressees are also in the series Litterae et Commissiones Levantis (HR-DADU-8.1) and Litterae et Commissiones Ponentis (HR-DADU-8.2). The subseries also contains examples of correspondence between the state authorities and the French military authorities in Dubrovnik (1806-1808).

There is scarce evidence of Jews in this subseries. The references can be found in several letters written by the administrator of the consulate of the Republic in Algeria, Naftali Busnak, to the Dubrovnik authorities (vol. 598, no. 111-118). References to Jews are also expected to be found in the correspondence of Republic authorities and its representatives in Rome, as well as in the correspondence of the authorities and the ambassadors of the Republic in the Ottoman cities.

There are no references to Jewish people in the series.
The series mainly contains minutes of decisions made during the sessions of the major and minor councils of various fraternities as well as a list of fraternity chaplains from the 17th to the beginning of the 19th century.

There are no references to Jewish people in this fonds.
The books of this fonds contain data on money investments in foreign banks and on interest income gained from these investments. The data mainly refer to banks (monti) in Italian cities such as Rome, Naples, Venice, Genoa, Palermo, Messina, and, since the 18th century, also to the banks in Vienna.

The fonds contains books of expenditures for the maintenance of the salt basins in the Dubrovnik Republic and the costs of the fees and salaries of state employees such as guards, weighers, porters, or noblemen who managed the Salt Office, etc. The fonds also contains registers of purchases of foreign salt, registers of sales of domestic salt, registers containing entries on payments of fees to boat owners who transported the salt produced in the Republic for sale to Gabela (the Neretva River) at the end of the 16th century and in the 17th century.

The bookbinder Manuel (Emanuel Coen), who in the early 17th and the 18th centuries bound books for the needs of the Salt Office (e.g., vol. 37, no. 45), is most likely the only Jew referenced to in this fonds.

There are no references to Jewish people in the series.
The series contains registers of marriage contracts made by the inhabitants of the island of Lastovo from the middle of the 17th century to the beginning of the 19th century.

The series contains official letters from the mid-18th century to the early 19th century sent by the Maritime Office to consuls and representatives of the Dubrovnik Republic in Italian, Ottoman, African, Spanish, and Portuguese ports. Due to a new increase of maritime affairs in the Republic at that time, the Republic of Dubrovnik had established about 80 consular offices in these ports. The series also contains circular letters and instructions to Ragusan sea captains, to all consuls of the Republic, and specifically to all consuls in the Ottoman Empire and to all consuls in the countries in the Western Mediterranean parts of Europe.

The series contains a small number of letters sent to Jewish people by the officials of the Maritime Office. Among those people, in the second half of the 18th century, there are references to the administrators of the consulates of the Dubrovnik Republic in Algeria, Abram and Raphael Jacob Bussara, (e.g., vol. 8, f. 3). There is also another reference to Abram Aruch, who was responsible for Ragusan ships in Alexandria at the time when there was no Dubrovnik consul in the city (vol. 1, f. 110).

The series consists of only one volume in which between 1799 and 1800 the purchase and sale of shares were recorded. Records of share trading contain the following information: date of sale, name of the seller, number and price of shares sold, name of the buyer, name of the captain of the ship the shares of which were sold. Share sales were most often recorded in a following format: Adi 2 Luglio 1799; Capitano Cristoforo Milich ha venduto caratti mezzo a Jacob Israel Russi per ducati settanta cinque nel bastimento diretto da quondam capitano Niccolo Marassi (vol. 1, f. 5).

The volume is very important for researching the history of maritime business of Ragusan Jews in the 18th century since almost all the Jews were co-owners of ships of the Republic at that time. Most of them owned 1/2 to 3 shares of one or more ships. The cases where Jews owned half of one ship (12 carats), or more, were very rare. Ragusan Jews sometimes had the ownership of the entire ship, and this data is recorded in the fonds Diversa de Foris (HR-DADU-30). There are many records in this volume in which Jews appear both as sellers and as share buyers. Most records refer to members of a Ragusan family Ambonetti, and other records refer to members of other Ragusan families such as Costantini, Levi Mandolfo, Luzzena, Maestro, Pardo, Russi, Tolentino, Valenzin, Venturra. The records show that even Ragusan women also traded in shares at that time, and some of these women were Jewish, such as Lydia, the wife of Israel Maestro, and Judith, the widow of Nathan Ambonetti (e.g., vol. 1, f. 30).
