Crie uma referência precisa em Chicago 18, 17 e 16
General rules
In contrast to the notes and bibliography system, Chicago Style – author-date (17th ed.) does not require transferring the main details of an archival document to notes or to an in-text citation. All the appropriate information on the archival material is given in the list of references using the following template:
Author of the document. "Title." Document location in the archive. Collection number and Title. Name of Archive, City.
Include the information on archive units such as folder, box, call number, etc. in the 'Document location in the archive' element. This data can be different from country to country or can be absent at all, which is often the case when dealing with digitised online archives.
For online documents, use the same template, adding the URL address at the end.
If an archival material does not have a precise title, give a descriptive title without the quotation marks instead.
