Just before Christmas, I wrote a post about the new facility on Art UK which enables one to identify the location of all the works by RAs in British public collections, all 25,000 of them.   When I got back from Christmas, I discovered that I had committed myself to writing about some aspect of Art UK’s involvement in our 250th. anniversary.   I chose to write at greater length about the benefits of the facility, what one can discover hidden away in British collections, and to celebrate those Cambridge colleges who have agreed to their collections being listed.   See https://artuk.org/about/blog/royal-academicians-on-art-uk-celebrated-for-ra250
