The following outline is provided as an overview of and topical guide to the real-world history and notable fictional elements of J. R. R. Tolkien's fantasy universe. It covers materials created by Tolkien; the works on his unpublished manuscripts, by his son Christopher Tolkien; and films, games and other media created by other people.
Middle-earth – fantasy setting created by Tolkien, home to hobbits, orcs, ents, dragons, and many other races and creatures.
Pictures by J. R. R. Tolkien (1979) – text by Christopher Tolkien. Most of these pictures had been previously published in calendars by Ballantine Books (1973) and George Allen & Unwin (1974, 1976–1979), some of them coloured by H. E. Riddett.
These works present extended selections of Tolkien's legendarium (the large body of documents relating to The Silmarillion), with extensive notes and posthumous editing by his son Christopher. The separate 4-volume body of his comments on the drafts of The Lord of the Rings is included as volumes 6–9.
