The Hobbit, or There and Back Again is a children's fantasy novel by the English author J. R. R. Tolkien. It was published in 1937 to wide critical acclaim, being nominated for the Carnegie Medal and awarded a prize from the New York Herald Tribune for best juvenile fiction. The book is recognized as a classic in children's literature and is one of the best-selling books of all time, with over 100 million copies sold. The Hobbit is set in Middle-earth and follows home-loving Bilbo Baggins, the hobbit of the title, who joins the wizard Gandalf and the thirteen dwarves of Thorin's Company, on a quest to reclaim the dwarves' home and treasure from the dragon Smaug. Bilbo's journey takes him from his peaceful rural surroundings into more sinister territory. The story is told in the form of a picaresque or episodic quest; several chapters introduce a new type of monster or threat as Bilbo progresses through the landscape. Bilbo gains a new level of maturity, competence, and wisdom by accepting the disreputable, romantic, fey, and adventurous sides of his nature and applying his wits and common sense. The story reaches its climax in the Battle of Five Armies, where many of the characters and creatures from earlier chapters re-emerge to engage in conflict. Personal growth and forms of heroism are central themes of the story, along with motifs of warfare. These themes have led critics to view Tolkien's own experiences during World War I as instrumental in shaping the story. The author's scholarly knowledge of Germanic philology and interest in mythology and fairy tales are often noted as influences, but more recent fiction including adventure stories and the works of William Morris also played a part. The publisher was encouraged by the book's critical and financial success and, therefore, requested a sequel. As Tolkien's work progressed on its successor, The Lord of the Rings, he made retrospective accommodations for it in The Hobbit. These few but significant changes were integrated into the second edition. Further editions followed with minor emendations, including those reflecting Tolkien's changing concept of the world into which Bilbo stumbled. The work has never been out of print. Its ongoing legacy encompasses many adaptations for stage, screen, radio, board games, and video games. Several of these adaptations have received critical recognition on their own merits.
