The books of this fonds are mainly from the second half of the 18th century. The fonds primarily contains books kept by the Office for Maritime Affairs and those kept by the Office for Consulates in the Ottoman Empire. The documents in the books contain lists of accepted and rejected expenses of consulates in Alexandria, Arta, Chania (Canea), Istanbul, Smyrna and Thessaloniki, a book of Senate decisions on consulates in the Ottoman Empire, a book with a list of Dubrovnik consulates and consuls and a book of letters written by the consuls to the authorities of the Republic. The collection also includes books that do not belong to this fonds, such as the expenditure lists of the ambassadors of the Republic in Istanbul and in Belgrade (17th century). The fonds also contains one expenditure list of a Ragusan ambassador in Vienna (1772), and one travelogue of an ambassador in Istanbul (1792), as well as a list of Ragusan trade intermediaries (sensali) (1572-1575).

Two volumes of the fonds are important for researching the cooperation of Jewish population with the Dubrovnik Republic. Volume 1, entitled Tasse per sansaria imposte à Sensali pubblici dell 'anno 1572-1575, shows that 72 official trade intermediaries operated in Dubrovnik during this period. Among them there were approximately twenty Jews, from Jewish families such Adaroch, Barochas, Berubi, Celebi, Chatinela, Cohen, Crispin, Flores, Gabai, Gratiano, Jachar, Mazza, Moscato, Nasin, Nahem, Oef, Pardo, Sabatai, Trincha and Zafarana. A particularly significant name referenced in the fonds is the name of Isaia Coen, a nephew of Didacus Pyrrhus (vol. 1, f. 32). The data also contain names of the merchants who used the services of trade intermediaries. Volume 2, entitled Consolati nationali 1752-1796, contains a list of Dubrovnik consulates and consuls at the time. Among them there are members of Jewish families Bussara and Busnaco, who served as administrators (amministratori) of the Dubrovnik consulate in Algeria (vol. 2, f. 77).
