Now that's curious. My copy of the book is the expanded 1932 set, edited by Maud Karpeles. She accompanied Sharp for the full 49 weeks. With "a few minor omissions" she reproduces Sharp's original introduction. She notes it was preliminary, written after only 9 weeks in the mountains.

She says (and lists) 32 songs, tunes & ballads from the collection of Olive for the 1917 work. She has a credit on the face page as contributing 39 of the 968 tunes in the final cut.

Neither she nor Sharp makes any further reference to Olive.

They both note that John Campbell was very helpful, went to great and generous effort and "gave us the benefit of his very full knowledge of the country and its people."

Certainly nothing to justify the slightest textual, musicological or bibliographical contribution, much less the "co-authored" that Desert Dancer found in the listing. (No dis to DD, obviously.)

Most of the information I have on Olive comes from the school's web site so I can't claim any great knowledge there but Sharp was certainly one of the greatest collectors and musicologists that ever lived. Imagine writing down the tune as it is sung, livetime!

And just was her relationship with Marguerite, anyway? Weren't they "traleling companions" through Europe?

Never mind. Just sassing.
