no , they probably didnt deliberately exclude them,but more likely didnt think that they had anything worthwhile to contribute,that decisions such as were made, were better made by the EFDSS or their representatives,Than by the people from whom the songs were collected

Dick the words "probably" - "more likely" - indicate that you are guessing their motives. No one is denying your expertise in the matter of the IFMC, although I seem to remember only a week or so ago you had no idea where the definition came from.

I don´t need to prove their motives, I am not imputing anything to them. You are, so the burden of proof lies with you.

Clearly your expertise in the matter of Maud Karpeles helpìng Sharp with "much of his collecting" is much greater than mine. Tell us which of his collecting she helped him with Dick.
