Have you tried contacting the publisher? I think Oxmoor still publishes.
Years ago, when eBay was in its infancy and Amazon only sold new books, I found a quilt book I wanted on eBay that was no longer in print. The bidding quickly skyrocketed to ridiculous numbers— 5 times list price— so I decided to try something different. I wrote to C&T, the publisher, to ask if I could pay a copyright fee to allow me to make a photocopy of the entire locally available library book.
A week or so later, I got a call from C&T. They had a few copies of the book they had found stuffed in a corner of the warehouse, but they were somewhat damaged, so they couldn’t sell them for full price. Would I be interested in buying a copy for half price? Why yes, yes I would. Still have the book on my shelf today.
