How did I find all this?
Using Google Scholar!
It took a surprisingly short time to gather all the material presented here. The most time-consuming part was just to write up all of these references in a proper style and translate the German ones. Getting a list of them was pretty easy just from here and here. I only started using Google Scholar recently, but it's an invaluable tool for finding academic references in literature and other subjects.
