Hello, I've recently come into copies of the Moon Design published Glorantha Classics Volume 1: Pavis & Big Rubble. And Glorantha Classics Volume 4: Borderlands & Beyond. And when I put them on my shelf my copy of Borderlands & Beyond is about a tenth of an inch taller than my copy Pavis & Big Rubble. My concern is that one of them is a knock off or POD copy. Both of the book's print are of exceptional quality and don't look POD. Unless POD quality has improved massively in recent years. I don't know where else to turn to find a question to this admittedly strange and obscure question. Thanks on advance.
Edit: I realize that these books have been printed since the late 90s. So maybe I have two copies that are 20+ years apart in terms of when they where printed and that I can tell when they where printed by looking at their front pages. But I'm in bed and will check tomorrow. Any insights you have dear reader will be valued regardless.
