I mean, I also have a one page setting sheet that my players can refer to during the game as needed. But I don't give them a 32 page (or more) book to read before starting an AP (which was what Paizo was suggesting back in the day at least). To me that's just nonsense, and if I were a player I probably wouldn't read it either unless the setting really grabbed me and I wanted to know more. Or I'd skim it at the table during the game just like my students try to get away with skimming any readings they've been assigned right before class starts
