Marco:

 Strange as it may seem, I am familiar with the procedure for searching for
 references to Cancellaria, etc.  I am really sorry to learn that my name
 appears only among homonyms as I know of only one for which I am
 responsible.

 The point I had hoped to make was that through the procedure listed, you
 immediately get thumbnail photos of what is on each site whereas in a
 "regular" Google search you have to click on each site (most of which do
not
 contain videos).  On neither "images" or "videos" do you get references to
 papers, books, etc.  I have not tried it, but I suppose that one could just
 type "snail images" in the search bar and achieve the same purpose.
