The Road to Middle-Earth: How J. R. R. Tolkien Created a New Mythology is a scholarly study of the Middle-earth works of J. R. R. Tolkien written by Tom Shippey and first published in 1982. The book discusses Tolkien's philology, and then examines in turn the origins of The Hobbit, The Lord of the Rings, The Silmarillion, and his minor works.
