Answering myself :) There is a new page (which I just set up today) on EmacsWiki called Research About Emacs, and also a Zotero group called Emacs for all your reference convenience.
The former1 is, hopefully and potentially a growing, maintainable, close-to-Emacs-community and also search engine friendly page for documenting, disseminating, organizing and debating research about and around Emacs. The latter2 is hopefully a growing, maintainable and also close-to-academic-community place for collecting Emacs references now and in the future.
This answers the question. Have a nice day, self, and enjoy the readings collected so far. So far they are
