The papers in question are called "intermittent copies" and the rules governing these copies were tightened some time ago. These copies make up a small number of copies in a limited number of papers and the papers are required to list these papers as a separate line item.
Just an FYI. I've been getting free papers, two days a week for several years, which doesn't come close to my definition of "intermittent" copies.
Your response seems to infer that the publishers self-report by filling out a form, and then are subject to be audited.
All said, I'm really not qualified to judge, so I'll trust the process is credible.
I know a lot more than when I first posted.
Thank you for taking the time.
