I think of these five very promising sources the last one, by Gary Westfahl, is going to be THE MOST promising because of the title. The “Evolution of Modern Science Fiction” is almost word for word my thesis, which is pretty awesome. Hopefully this article by Mr. Westfahl will be abounding with just the information I need (I have a good feeling that it is).
