"John Ronald Reuel Tolkien (1892-1973) was a brilliant writer who continues to leave his imaginative imprint on the mind and hearts of readers. He was once called the "creative equivalent of a people," and for more than sixty years his Middle-earth tales have captivated and delighted readers of all ages from all over the world. The Hobbit has long been recognized as a children's fantasy classic, and the heroic romance the Lord of the Rings has been called the most influential story of all time. These stories have sold over 150 million copies worldwide and have been translated into over forty languages, and they, along with works such as the Silmarillion and the History of Middle-Earth, have convinced scores of readers and critics that Tolkien is the master writer of fantasy. Whether you've been a fan for years or you've just recently been hooked by the blockbuster Lord of the Rings movies, "I Am in Fact a Hobbit" is an excellent starting point into the life and work of J.R.R. Tolkien. Book jacket."--Jacket.

"The Road to Middle-earth, Tom Shippey's classic work, now revised and expanded in paperback explores J.R.R. Tolkien's creativity and the sources of his inspiration. Shippey shows in detail how Tolkien's professional background led him to write The Hobbit and create a timeless charm for millions of readers. He argues convincingly that the source of Tolkien's inspiration lay not just in his love of fable but in his love of language. While examining the foundations and literary structures of Tolkien's most popular work, The Lord of the Rings, in rich detail, Shippey also discusses the contribution of The Silmarillion and Unfinished Tales to Tolkien's great myth cycle, showing how the more "difficult" books can be fully appreciated. He goes on to examine the remarkable twelve-volume History of Middle-earth, written by Tolkien's son and literary heir Christopher Tolkien, which traces the creative and technical processes by which Middle-earth evolved."--Jacket.
