By the way, did you know there is even a Wiki for the works of J.R.R. Tolkien?
I was once involved in a project doing in-depth analyses of The Lord of the Rings. It was a very fun project, but required a great deal of research and thought. I haven't stepped back in to work on it in a long time, and activity on that site has dropped off quite a bit, unfortunately.
But I was happy to find this LOTR wiki, even though its information only skims the surface, it is a nice reference source when you are racking your brain about some piece of the epic.
