You can be a painting tagger! The Public Catalogue Foundation has a vast online treasury of publicly-owed art in the UK (It's called Your Paintings, but it's not all paintings).. They're asking for people to come in and help tag the work. It's really fun. I spent more time than I should trying to track down a term I couldn't remember (I failed: it's that board piece that Elizabethans put into their pairs-of-bodies to make the front of the dress be stiff and flat),
In the interest of economy, I'm tagging this citizen science. What? History is a science. Or ought to be.
