Thanks for the info, Roope. I was able to purchase a copy of the 2nd Library Covers book from Trunk, but I'd not heard of Unusual Sounds until you wrote about it above.
A couple of Google hits took me to this place: h$$ps://shop.mexicansummer.com/product/david-hollander-unusual-sounds/
I'm currently consulting my check book to see if I can indulge in a copy of this book. I may have to perform an unnatural act (or 2) or worse, perform the "Forbidden Dance."
I'll keep you posted cuz I'm sure you're just on the edge of your seat, with anticipation...
