The works on Middle-earth published by Tolkien during his lifetime include "The Hobbit", "The Lord of the Rings", "The Adventures of Tom Bombadil", and "The Road Goes Ever On". After Tolkien's death his son Christopher published "The Silmarillion" with many textual changes to knit several mostly unfinished manuscripts together as a coherent narrative. Further posthumous publications (with text more closely following Tolkien's original) include "Unfinished Tales", "The Letters of J. R. R. Tolkien", "Bilbo's Last Song", "The Children of Húrin", "Beren and Luthien" and "The Fall of Gondolin".
