I think this article may not have reliable sources, but it deserves to live at least because of very concise and elegant definition of it's subject. Even if this is an original investigation, I suppose that it has no chances to be published standalone, yet contains useful information. I myself being logician haven't even realized that S and K combinators can be written in prefix codes in this way. But it's so obvious and elegant.
