I came across this when I was looking for local pictures on Flickr. Douglas Campbell was an amateur photographer who left over 30000 slides when he died in 2007. His son is attempting to have them all digitised and put them on Flickr, he is approaching 10000. The sets are divided into years, going back to the 1950s, and there are many pictures of buildings.
