I just got two new books from my parents yesterday. "The Essential J.R.R. Tolkien Scorebook - A fan's guide to Middle-Earth and Beyond" by George Beahm and "Lord of the Rings - The Art of The Two Towers" by Gary Russell.
The first one is neat. It has a description of every book/movie writen by/about Tolkien. The second one is very pretty. It has a ton of drawings and scetches from Alan Lee and John Howe, and beautiful costume designs from Ngila Dikson, and a lot more.
They are both very interesting.
