I'd gone to Goodreads, as is my usual practice, and linked to you for the book "The Economics of Discrimination," by Gary S. Becker. I was asked to sign in but wasn't returned to the book page and the message said there were no available copies.
However, when I went back to Goodreads and linked in again there was the page I'd first seen with the list of this book. I hope that it is actually available and will arrive! :O
