Records for some comunes in Catanzaro recently added (16 Nov 1911). Record images available; they are not indexed but can be browsed. I'm currently checking for my paternal great great grandparents and ancestors from Feroleto Antico.

I've spent the last week going through many of the towns there as well. I also found a few Catasti extractions that weren't online before on www.archicalabria.it/Default.asp
You might want to have a look there to see if anything helps. Side note: You need to play with the search engine because it's a bit quirky. The extracted records will now show up if you hit certain links first. Let me know if it helps you at all or if you have any questions.
