I had an article that ran on a website named Indicommons in 2009. I resurrected it and posted it to my own website in 2015.
Indicommons was a group of lovers of the Flickr Commons, sharing information about what's going on and what's inside. My article discusses a set of 130ish year old photos posted by the New York Public Library. I've posted comments with information about the locations to a number of photos, and on my last trip to Tokyo I visited several spots to take the same scene today. By chance there was an exhibit with more photos from the same studio which I visited on the trip as well.
