Lore books require players to actually read them. They don't do a lot of good if the player just picks them up, and stores them somewhere, or sells them. A Glossary/Encyclopedia will be subject to the same shortcoming. If a player doesn't use it, they're going to be in the same boat the OP is in here. When I'm playing a new IP, I read all provided lore, I even go so far as to seek out any books provided, in game. If there's a glossary/encyclopedia, I'll read it, but, and there's always a but, I have to do it. Even something like providing hyperlinks in dialog is useless, if the player doesn't click it. At some point, the player is going to be expected to do some footwork, if they want to be informed.
