The seeds of The History of Middle-earth were sown in the 1970s, when Christopher Tolkien began working on a comprehensive guide to his father's mythology. The project evolved into a massive 12-volume series, which was published between 1983 and 1996. The series includes:

The 12 volumes cover an enormous breadth of material, from the earliest stories of the Elvish awakening to the detailed chronologies of the Second and Third Ages. The first two books, The Book of Lost Tales , contain the first narratives of the Valar, Elves, and Men, written decades before the publication of The Lord of the Rings . Subsequent volumes trace the evolution of The Silmarillion and provide a detailed history of the writing of The Lord of the Rings , showing how the story of the Ring evolved from early drafts to its final form. The final volume, The Peoples of Middle-earth , includes the development of the Appendices to The Lord of the Rings , Hobbit genealogies, and other late writings from the last years of Tolkien's life.
