The fonds contains accounting records of the expenses of the orphanage such as the payment of fees to breastfeeding mothers and other employees as well as the expenditures for the purchase of clothing for orphans, the baptismal records of orphans, books of agreements on breastfeeding and foster care, books containing lists of names of children living in the institution, books with records of the arrival of pregnant women at the institution (without mentioning the names of these women). These books date from the late 16th to the early 19th centuries.

The fonds contains very little data on Jews that can be used for the analysis of their work in the public and state services of the Republic. Namely, there are references to Jewish bookbinders who in the 18th century made books for the needs of this institution. The bookbinders were members of some Ragusan Jewish families such as Coen, Fermi, and Vitali (e.g., vol. 14, f. 1).

The fonds consists of two parts. The first part contains 14 registers of the movement of people and goods through the Lazarettos in Ploče, in the eastern suburb of Dubrovnik (18th century). Those registers were kept by the Captain of Lazarettos. The registers contain the following information: the date of the passenger's entry into the Lazarettos, the name and surname of the passenger, the name of the place from which the passenger arrived, the list of merchandise the passenger had brought, the number of the specific lazaretto where the passenger would be quarantined and the date of release from quarantine. The second part of the fonds (16th-18th centuries) consists of volumes with the following data: provisions of the Office of Public Health and the Senate which were related to the protection against the plague, expenses of the Office, investigations conducted by the Office of Public Health against persons who violated the measures for the protection against plague, and lists of health officials who were deployed throughout the territory of the Republic at the time of the danger of the plague.

The registers containing data of the movement of people and goods through the Lazarettos in the 18th century are very important to the research of the business affairs of the Jews from Sarajevo as well as for understanding their relationships with the Jews from Dubrovnik. Many of these records testify about the arrival of Jews in the Lazarettos almost all of whom came from Sarajevo (e.g., vol. 11a, ff. 10v, 39, 39v, 41v, 48v, 59, 64, 74v, 76, 80, 81, 82c, 85, 91c, 97, 101c, 102c, 103, 104, 109, 116c, 127). The records show that most of these Jews were originally from Dubrovnik and were returning home from Sarajevo, and there are also records of Jews from Sarajevo who would come to Dubrovnik for private or business reasons. There are also references to members of the following Jewish families: Abinun, Abramović, Altarac, Asser, Atias, Campos, Cohen, Danon, David, Escenasi, Fermo, Finzi, Forte, Franco, Gabai, Gaon, Haion, Joel, Jona, Levi, Montiglio, Musafia, Musafir, Papić (Pappo), Pinto, Saba, Saltiel, Seferović, Tedeschi, Tolentino, Vitali and Zevi. Apart from the Lazarettos, other facilities located in the suburbs of Ploče were also used for the purposes of quarantine. Among those buildings was the house of a famous Dubrovnik merchant Samuel Ambonetti. His house has been used as a quarantine area since the late 1750s, and the data shows that it was named the “old Ambonetti lazaretto” (e.g., vol. 7, f. 13v). There are less references to Jews in the second part of the fonds. Those references are primarily to Jewish bookbinders who bound books for the needs of the Office of Public Health. There are also references to the taxes imposed on the Dubrovnik Orthodox community and sea captains from Dubrovnik as well as taxes imposed on the Jewish community for the costs of protection against a very strong plague epidemics that ravaged the Dubrovnik hinterland in the 60s and the 80s of the 18th centuries (e.g., vol. 2, August 20, 1767). Particularly interesting is the reference to Abram Abuaf, who in 1691 during the epidemic, treated plague patients in the city of Dubrovnik (vol. 7, f. 12).

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).

There are no references to Jewish people in the fonds.
The Maritime Consulate recorded statements about damage at sea caused by natural disasters, and attacks by pirates and corsairs. Testimonies were given by captains, crew members and passengers of both Dubrovnik and foreign ships, whose first port of call after the accident was Dubrovnik. Based on these statements, cases of a property-legal nature were resolved, primarily due to the need to collect maritime insurance. The fonds covers the period dating from the 20s of the 17th centuries to the beginning of the 19th century.
