The best way is, of course, to read the books. We prefer all players to have read at least A Game of Thrones.

But even if you have read all the books, keeping all the information about the series fresh in your mind is easier said than done. The Citadel is the section of Westeros where we have collected thematic resources, such as the Concordance, which is a compilation of just about every little piece of thematic information from the series made specificially with this MUSH in mind.
