Are you a fan of books?

Yes, but I actually think you could turn it into a really good story aspect.
Let's say you have to find something out that there's no surviving record or memory of in Nirn (kind of like Dragonrend). You know the name of it, but that's it, so to find out more, you have to venture into Apocrypha, and sort through rows upon rows upon rows of books, with no idea which one of them is actually the one to help you out. Apocrypha could house every book that's appeared so far in the series, as well as some brand new ones and even books written only in Daedric or other languages just for variety.
What could make this process annoyingly awesome is if Radiant AI/Storytelling picked a different part of the library each time for the information you needed to be housed. If that were the case, it should be an optional (and fairly long) sidequest to lead you to something really powerful.
