Also, I don't know why he needed to order ISBN's in advance
I have no idea about publishing, and I suspect that you would be in the minority of the community who does know. When you don’t know something, this kind of information seems legitimate. It’s this kind of thing that makes me mad, as it would seem that he was even taking advantage of vulnerable people back then 🤦♀️
Edit: I did a little research about isbns and I can’t believe he embellished like he did. Sometimes his bs even surprises me!
