Unfinished tales of Númenor and Middle-earth

More about the book

"Presents J.R.R. Tolkien's elaborations beyond 'The Lord of the Rings' and 'The Silmarillion' regarding the lands of Middle-earth and Numenor, with an introduction, notes, maps, and a glossary-style index by Tolkien's son Christopher." "This book was not planned by Tolkien and is a disparate collection held together by the continuing editorial presence of his son Christopher; his exhaustive commentary and countless footnotes are learned and helpful ... the nature and state of this material give us a rare glimpse of how Tolkien developed his fantasy world over the years."
