I noted your post on British Photographic history about the Reflections On A Glass Plate symposium.
I'm a retired astronomer, living in Australia, so it's unlikely I'll be there on May 17 -- incidentally the BHP page does not have a date for the event. However, you may care to know that astronomers were early users of glass plates after the dry plate was invented, and continued to use them until the late 1990s. As a consequence there are several large archives of plates around the world, some representing a 100 years of observations.
I used plates from 1975 until ~1997, and made the first 3-colour images from the using a variation Maxwell's additive 3-colour process.
In the UK I'm aware of the UK Schmidt archive at the Royal Observatory Edinburgh, which contains ~20,000 14 inch-square plates, the last taken in 2002. I no longer have a contact there, but you might like to to let them know about your meeting.
