I didn't get as far as you have, a matter you may remember our talking about (got a pretty good architectural publisher, at that moment in time, who said yes. I couldn't follow through because of changes in my life. I'm not all that sorry now, since my interest in piazzas wasn't about writing a book, but about learning about them and their effect on cities or towns large or small. Yes, ultimately a book possible, as when I looked online there was eh going on.
Far as I know, there is still not a major book, academically or otherwise, about piazzas.
I had 39 outlines...
I gave up when I moved north, as usual a financial decision. There I was quickly caught up in having a design business and art gallery business with a woman I knew as very capable. I was the one who paid for our getting the place. She was smarter re money.
I still have my data and a zillion books and my photos.
I prefer not to throw them out.
