I have a copy I got back around the year it was published, by Rutherford House I think. It is a straight reprint of the typed dissertation. I presume the text has never been put into etext. But all it would take would be sending a copy to a POD publisher to keep it available I would think. It's a pity it is not formally published; though I would not want to be the one to reset the text (not for free certainly

).
