There are two ways to read Tolkiens works. Here is the first way: The Hobbit, then The Lord of the Rings trilogy, then The Adventures of Tom Bombadil (if you like poetry), The Silmarillion, The Great Tales Trilogy (which is three books, The Children of Hurin, Beren and Luthien), and finally Unfinished Tales. If you like some less complicated works by Tolkien I would recommend reading Tolkiens books this way: The Hobbit, The History of the Hobbit, Roverandom, and Tales from the Perilous Realm.
