Phew, just finished reading the document I got in the post the other day all the way from the US, about the Anthropic settlement (for them downloading books from pirate sites to use to train AI.)
Need a cuppa to recover from that much legalese. But it looks like I can make a claim. From a cursory check, I've got 3 books on the Works List, all of which I was the sole owner of at the time, as the rights had reverted to me. A few years before.
