Inspired by this question, which asks for a list of students who were expelled from universities in Nazi Germany, I would be interested in knowing where I might be able to find more information about doctoral theses that were passed between 1933 and 1945 - specifically, those that dealt with racial science and other matters of a politically- or socially-charged nature.
Was there a noticeable increase in dissertations that dealt with the Jewish question during this period? Was there a marked rise in papers that looked at issues like Communism, the Trade Unions, homosexuality, criminality, disability, etc? I would very much like to know (assuming this sort of research has been done) by what percentage these sorts of studies increased, and whether or not (and by what percentage) they decreased again after '45.
I am specifically looking for doctoral theses, but studies that concern general academic literature during this period may be of interest too.
