Yaay for random questions!
I keep all me Tolkien books in my room on a little 3 - 4 ft bookcase.
My preciousss--es. 
In this order:
On Top (shelf 5, I suppose): The Lord of the Rings.
(shelf 3 has LotR goodies
)
Shelf 2 has: The Hobbit, The Book of Lost Tales I, The Book of Lost Tales II, The Shaping of Middle Earth, The Return of the Shadow, The Treason of Isengard, The War of the Ring, Sauron Defeated, Morgoth's Ring, The War of the Jewels, The Peoples of Middle Earth, The Silmarillion, The Tolkien Reader.
*pant pant*
....And Shelf 1 has LotR Board games and my elvish notebook.
Whooo-hooo for Tolkien geeks!
Which meant that last time I read them I couldn't find Return of the King. 
) and so are The Appendices and Middle-Earth for Dummies (I'm no Dummie, but it's a really good book!)
)
