The series contains various accounting books and lists of state revenues from the 15th to the 19th century. In six volumes, the costs of missions to the sultan and Ottoman dignitaries from Bosnia to Istanbul were recorded, as well as the costs of missions to the Venetian general provider of Dalmatia (18th century). After a thorough consideration, accounting officers either accepted or rejected the costs, and recorded accordingly those expenditures in notebooks bearing the names Partite accetate and Partite ributtate. Rejected expenditures were sent to the Senate for further consideration.

There are only few references to Jews in this series. Those references can be only found in volumes no. 11 and 12, entitled Riscossioni dell'Officio (recoveries of state revenues, 1711-1740). In these references Jews are referred to mostly as tenants of residential and commercial premises belonging to the foundation Opera pia. A very prominent Dubrovnik merchant Raphael Coen, as well as his sons Abram and Aron (e.g. vol. 11, f. 28) are those Jewish people mostly referred to in these volumes.

The fonds consists of treasury journal and accounting books of the Foundation from the 14th to the 19th centuries. These documents contain data on calculations of income from principal invested in foreign banks; calculations of income from renting residential premises, business premises and land. They also contain books of expenditures and income and accounting books of individual foundations that were an integral part of the Foundation Opera pia. The fonds also contains books with official letters written by the state treasurers and legal representatives of the Cathedral to Dubrovnik consular and diplomatic representatives, agents and confidants in Italian and Ottoman cities and in Vienna (Copia lettere dei Signori Tesorieri e Procuratori di Santa Maria Maggiore). Primarily, the topics of these letters were financial investments in Italian and Viennese banks, or investments in the Venetian mint and companies in charge of customs leasing, or in charge of the purchase of expensive Italian fabrics and fragrant oils intended for diplomatic gifts to Ottoman dignitaries; financial transactions for the settlement of the tribute to the Ottoman sultan; and for slave redemption.

The fonds does not contain a large amount of data on Jews, but the data in the fonds primarily relate to the private and business lives of the Dubrovnik Jews, as well as to their cooperation with the authorities of the Republic. Part of the data can be found in the income books of the foundation, in which the revenue from renting apartments, business premises and land is stated. References to Jews can also be found in the books of maritime affairs (18th and 19th centuries). The books contain references to Ragusan Jewish families such as Ambonetti, Cittanova, Costantini, Janni, Levi Mandolfo, Maestro, Pardo, Russo, Tolentino, Valenzin (vols. 25, 58, 36, 111, 118, 119, 125, 134, 135). In these documents the Jewish community appears as a debtor for business premises (1811-1812) (vol. 135, index, letter S). Two volumes are particularly important for the research of business affairs of the Jewish population in Dubrovnik: vol 125 (Conti Marittimi del 1789; Arboracci, Divisioni e Rimese), which lists the co-owners of Dubrovnik ships and their co-ownership shares in the period from 1789 to 1794, and vol. 134 (Libro di Negotio del 1781) in which Salvator Levi Mandolfo and Benedict Volterra are repeatedly mentioned as traders in leather, wool, and rice (e.g., vol. 134, f. 29). One part of the data that provides the information about the Jews, which speaks of their cooperation with the state authorities, is found in the books that contain letters of the treasurers of the Cathedral to the agents and confidants of the Republic in Ancona. There are references to Jews in the 18th century, mostly to Aaron and Moshe, who were the sons of an eminent Dubrovnik merchant Raphael Coen. Reference is also made to Raphael's grandson Felix. Aaron, Moshe, and Felix lived in Ancona and performed various jobs for the Opera Pia Foundation (e.g., vol. 40, August 30, 1790).

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).

There are no references to Jewish people in the fonds.
The fonds contains monastery accounting books, books of the Dubrovnik Archdiocese and various decisions of church administrative bodies (e.g., decisions on the organization and daily activities of monasteries). The books of the fonds were created in the period from the 14th to the beginning of the 19th century.

The fonds is very important for the research of the history of Jews in the times of the Dubrovnik Republic since it contains two volumes related to Didacus Pyrrhus. Volume no. 42 contains a transcript of Didacus's poem De Rhacusinae urbid laudibus Carmen from a book which had been printed in Florence in 1613. Volume no. 95 contains a transcript of a short debate on the life and work of Didacus Pyrrhus, entitled Della vita e degli scritti di Didaco Pirro, altrimenti detto Jacopo Flavio Eborense. The text was written by Tomo Krša, a Dubrovnik writer and translator (1782-1826) and it was published in 1826 in Florence in _Giornale arcadio di scienze, lettere ed arti (_vol. 32, 1826). This fonds also contained a volume entitled De Didacho Pirro, Appunti which has been long lost.
