Hi, Mark -
Yes, that's the one. And yes, I'm looking for somebody to post the whole index. Most of us who do this regularly, scan the index and OCR the contents, and then post it and proofread it online.
If you can't do that, hold off for a while because there's bound to be somebody here with both the book and the OCR ability.
I'm surprised this book hasn't been posted online. Some of the other Lomax books from that period are online, but not on US Websites. I've checked the Plymouth Library and UTK song indexes, and the book is not indexed at either site.
