Hello, what a great new resource! Just trying to figure out how to best use it, and thought I would start by asking for your help. 

I am looking for photographs from the 19th and early 20th century categorising and showing homosexuals as pathological and recognisable by certain characteristic features (eg. as Lombroso did with criminals). I know they exist, and have found a few in a book called Psychopathology by Edward Kempf from 1921. Has anyone come across others? Suggestions of which archives might be useful?

Many thanks, and looking forward to seeing this network grow!
