The Shaping of Middle-earth: the Quenta, the Ambarkanta and the Annals (The History of Middle-earth, Vol. 4)

THE HISTORY OF MIDDLE-EARTH
Poems and prose, maps and chronologies, detours and diversions along the road to Middle-earth . . . Christopher Tolkien has gathered archival materials that his late father, J. R. R. Tolkien, used to create the world and the history behind his classic stories.
THE EVOLUTION OF A WORLD
This fourth volume of The History of Middle-earth presents early versions of those first tales, from the creation myth to the fall of Morgoth. Writings include a chronology of the events in Beleriand, the first Silmarillion map, and the only known description of the physical nature of Middle-earth's universe. Detailed annotations highlight changes ranging from the spelling of Elvish names to pivotal emendations whose effects reach even to the war of the ring.
The Shaping of Middle-earth presents a solid framework by which to trace the development of the early lore of Middle-earth. It is a truly indispensable reference work for those familiar with the history of that endlessly beloved land--and fascinating reading for those just entering that world.
