The correct Archive work is at:
For some reason the works of the series are all under "Biblioteca storica del risorgimento italiano . . . "
They name the works by Series and Issue number at the end of the "name"
Biblioteca storica del risorgimento Italiano da T. Casini e V. Fiorini: Ser. 1-8 (Volume 2, ser.6)
Then, for whatever reason, this has volume first and series second, and - for the actual file name - they put the series number at the front of the file and the volume at the end (so that is why the file name is s6bibliotecastoric07casi - or - s6 [for series 6] bibliotecastoric [form of title] 07 [ for volume 7] casi [shorten form of author Casini] ).
From the full Archive.org list there are some interesting titles; see the list at:
