It’s only just over a year since my book on art museums was published. It seems longer ago, partly because the text was delivered on 31st. March 2020, a week after lockdown and so inevitably reflects a more confident and optimistic era. I added a final conclusion to reflect the changes which I could see were coming. It is possibly too apocalyptic. But I hope the book still stands as a historic record of museums as they developed in the post-war era, becoming ever bigger, more architectural, more civic in their view of their responsibilities.
