The current arrangement dates back to 1932 when the papers were transmitted from the State Archives of Naples to the State Archives of Turin.

The papers have been cited by many scholars over time. It was therefore considered appropriate to proceed with a virtual arrangement, leaving the documentation in the historical locations.

The virtual reordering we present take advantage of the ancient lists of the documentations transmitted by the consuls in Constantinople in the 1880s to the Ministry of Foreign Affairs and of the numerous ancient reference numbers/codes. The reordering had as its aim the reconstruction of the last organization of the papers.

According to the new arrangement the archive consists on eight nucleus of papers with extremely variable consistency, sometimes divided into sub-series or groups of files
i) Laws and regulations
ii) Correspondence (forwarded letter books; received letters)
iii) A small number of files certifying the protection and assistance offered to Nationals
iv) A register compiled in order to supervise the Merchant navy
v) Two registers compiled in order to control passports and attesting the civil services
vi) Consular affairs, mainly contentious. The series includes registers aimed at managing protests and successions
vii) The papers produced during the Regency of the Consulate of Gran-Duchy of Tuscany in Constantinople (1859-1862)
viii) Miscellaneous

In drawing up the inventory it was deemed appropriate to give a single string numbering per archival unit, i.e. per file /register. This numbering makes it possible to quantify the consistency of the archive and to describe the files regardless of their physical location.
Inside the quotation marks are reported the original reference codes (numbers and/or dates) which made the reordering possible.

Between 1857 and 1858 there is a change in the ordering method of the 'consular affairs' papers. They are no longer folded in files. The documentation is collected in protocol order. Today, in the absence of the registers that served as a guide to finding the subjects of the papers, the only way to know the content of the documentation is reading them.
Subsequently (1859-), the filing system of folding the documentation was established again, without reporting the contents on the front of the folder. The filing, in this case, involved a complete, albeit quick, reading of the papers.

The Diplomatic Historical Archive of the Ministry of Foreign Affairs preserves at least two registers which were started in the 1850s and continued during the subsequent management of the Italian Consulate. I thank Dr. Claudio Maria Mancini who pointed out to me those documents. They are described in this inventory (nn. 41 and 44 ) as well as the register (n.15) preserved in SALT Research Archives in Istanbul (https://archives.saltresearch.org/handle/123456789/1581?locale=en)

Considering the numerous gaps, it cannot be excluded that part of the documentation may still be preserved in Istanbul at the producing office (now the Italian Consulate).
