Brian Herbert's novels include Sidney's Comet, Prisoners of Arionn, Man of Two Worlds (written with his father), and Sudanna Sudanna. In 2003, Herbert wrote a biography of his father titled Dreamer of Dune: The Biography of Frank Herbert. The younger Herbert has edited The Songs of Muad'dib and the Notebooks of Frank Herbert's Dune. Brian has also created a concordance for the Dune universe based on his father's notes, though, according to the younger Herbert, there are no immediate plans to publish it.
