Thankyou for taking the trouble to post.
Yet to receive a reply from local agencies, in the areas that look most promising.
But you will never know, unless you post a request, who might offer to assist you.
In the past I have received a reply from the most unlikely of places.
Many years ago a director of the TOMSK STATE UNIVERSITY, sent me some Russian research papers that I was trying to hunt down, as they discussed the application of a Kiwi invention.
Then there was the problem of getting them translated, as there were/are several different keyboard configurations used, to digitize the Cyrillic font.
Then more recently on a remote West Auckland beach, I passed the time of day with an elderly gent who told me he had emigrated from a far Eastern village, in the Soviet Union. I said I had no knowledge of the area he was talking about, but had, in the past, received a reply to an international request for help, from TOMSK University Library.
His eyes lit up in surprise, and he stated that was the university he was sent to for further education, at great distance from his home. Then he asked if I remembered the name of the librarian who had taken the trouble to reply, and was doubly surprised.
Shaking his head in disbelief, he explained to me that his best mate, through his years of study at that university, had married the lady who had emailed me.
The world is a very small place when it comes to research.
Alan.
