If it's static data, you could simply have a JavaScript tab with all of the information. It might make the game a little bit slow to load, but it should be fine. The state object would normally be the way to go to store dynamic information between sessions, but that is absolutely not an acceptable method for storing a large amount of information, since state gets written to the server every five seconds or so. If you must have dynamic data and you have a lot of it, one possibility might be to store it in one or more handouts.
