I can answer questions about all six Lord of the Rings books. I can also answer some about the Hobbit, the Children of Hurin, and Silmarillion. Also I can answer questions about the geography of Middle Earth in the third age. I can also answer any question about all three movies and the people who play any of the characters. Also if you need any information about the upcoming movie The Hobbit but are unsure of where to find it I can direct you there.
I have read many of J.R.R. Tolkien's books on Middle Earth and some of Christopher Tolkien's books on Middle Earth.
I have not studied Lord of the Rings, however I have read the Atlas of Middle Earth, the A-Z of Tolkien, the Children of Hurin, the Hobbit, and Lord of the Rings (several times).
