J.R.R. Tolkien, creator of the languages and history of Middle-earth as recorded in The Hobbit, The Lord of the Rings and The Silmarillion, was one of the most prolific letter-writers of the last century. Over the years he wrote a mass of letters—to his publishers, to members of his family, to friends, and to “fans” of his books—which often reveal the inner workings of his mind, and which record the history of composition of his works and his reaction to subsequent events.

A selection from Tolkien’s correspondence, collected and edited by Tolkien’s official biographer, Humphrey Carpenter, and assisted by Christopher Tolkien, was published in 1981. It presented, in Tolkien’s own words, a highly detailed portrait of the man in his many aspects: storyteller, scholar, Catholic, parent, friend, and observer of the world around him.

In this revised and expanded edition of The Letters of J.R.R. Tolkien, it has been possible to go back to the editors’ original typescripts and notes, restoring more than 150 letters that were excised purely to achieve what was then deemed a “publishable length.” and present the book as originally intended.
