Back now and back working on research. I found this book in Oxfam and couldn't resist so its the next on my list. Not directly related to the square as far as I know 9and nothing in the index) but as a contemporary architect there is no doubt some useful stuff in here on Liverpool in the nineteenth century. I shall report back, promise.
Back to work tomorrow so will be nice to see the square in person again. I've missed you, old friend!
