The fonds is an important source for researching the life and business affairs of the people living in the Dubrovnik Republic in the period from the 15th to the 19th century. It consists primarily of accounting books of debts and receivables (dare et avere), trade journals (giornale), various notes (squarçio, libro picolo, quaderno), general ledgers (libro grande, maestro) and accounting books of different stores (quaderni stacionis).

Volume no. 23 of this fonds is an accounting book which contains various monetary claims of Isac Vita Campos, with an alphabetical index according to the first names of his debtors. It can be assumed that this book contains data on both Isac and his brother Samuel, two prominent Dubrovnik merchants who ran a very successful trading company in the 18th century. The data provide evidence that seven generations of the Campos family lived in Dubrovnik from the 17th to the 19th century. Some accounting books of various Dubrovnik merchants, for example Vicko Stefani, Martolo Đurđević and Benko Resti, also contain data on their affairs with Jewish business partners (vols. 32, 43, 44).

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.

The fonds mainly contains data on court cases with topics that could be potentially sensitive or even dangerous for the stability of the Republic, and which were the responsibility of the Minor Council. Some of these cases thus reference to investigations led against local people who, together with Uskoci, plundered the neighbouring areas under the Ottoman rule, or to investigations against those who would spy for foreign countries. This fonds also contains documents that are not of a political nature, such as, e.g., wine smuggling, quarrels, insults, and physical confrontations.

There is very little reference to Jewish people in the fonds. Some references can be found in a lawsuit and a related investigation against a sea captain from the Republic who in 1547 attempted to kill some Jewish merchants on his ship (vol. 5, f. 13), and another reference found is in a reported conflict from 1550 between a Dubrovnik physician Isaac and other Dubrovnik physicians (vol. 5, f. 164).
