Three additional small sketches appear in Words, Phrases and Passages in Various Tongues in The Lord of the Rings, a list and commentary compiled by Tolkien after the publication of The Lord of the Rings, perhaps initially in response to a list of names, places, and words compiled by a librarian in Scunthorpe, Lincolnshire in 1959. The work was published in 2007, edited by Christopher Gilson, as Parma Eldalamberon 17. On p. 22 is a sketch of Tol Brandir between Amon Lhaw and Amon Hen; and on p. 36 are a sketch of the peak of Caradhras, ‘tapering upwards (like Matterhorn)’, compared with a sketch of Celebdil, ‘simply crowned by a smaller pinnacle’.
