The series mainly contains data on commercial credits, which were registered in the period from the end of the 13th to the beginning of the 19th century. The records include date of the credit agreement, name of the creditor, name of the borrower, amount of the credit, duration of the credit, and contractual clauses of the credit agreement. The interest amount is not entered. Those who wanted to take a loan and did not reside in the Republic, and still wanted to register the credit agreement at the Public Notary of the Republic, could do this through their legal representative.

The series is very important for researching business transactions of Jewish people in the Balkans and the Mediterranean, as well as for a possible historical reconstruction of their commercial network, especially since the period of the early 70s of the 16th centuries, when the Jewish population in Dubrovnik significantly increased. Some well-known and very prominent members of the local Jewish community are referenced to in the series, such as Aron Coen and Abraham Coen de Herrera (i.e., vol. 96, f. 20v). In general, the series refers to members of the Dubrovnik Jewish community such as Abenun, Coen, Danon, Lanciano, Maestro, Miranda, Oef. Some Jews who were referenced did not live in Dubrovnik, but, overall, all Jews who are referenced in the documents occur in both functions: as creditors and as borrowers. In an attempt to better understand the significance of this series for the overall history of the Sephardim, it is advisable to refer to the doctoral thesis of Benedetto Ligorio (Roma, Sapienza, 2017), in which the author analysed the existing archival data on credits referencing the Jewish population between 1560 and 1654. The analysis of Ligorio provides relevant data that prove that in most of these documents Christians (primarily Dubrovnik noblemen) were stated as creditors for Jewish people.
