I've checked libgen, sci-hub, IRC... I'm not on any private book torrent trackers, but I assume they won't be there either. $80 is a bit too rich for me to pay for access through Guilford Press, although if I did that I'd download them all (last two years they make available) and then upload them somewhere.
Frankly, it angers me I can't read the articles, cause a lot of them sound good and interesting.
I think that refers to people who have already "bought" a subscription through their institution. A professor with legal access can print out an article for students. I don't think it allows the authors to send it to any student on the planet.
