The Hobbit, or There and Back Again is a children's fantasy novel by English author J. R. R. Tolkien. It was published on 21 September 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 remains popular and is recognized as a classic in children's literature.
The Hobbit is set in a time "between the Dawn of Færie and the Dominion of Men", and follows the quest of home-loving hobbit Bilbo Baggins to win a share of the treasure guarded by Smaug the dragon. Bilbo's journey takes him from light-hearted, rural surroundings into more sinister territory.
The story is told in the form of an episodic quest, and most chapters introduce a specific creature or type of creature of Tolkien's geography. 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 the 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 fairy tales are often noted as influences.
The publisher was encouraged by the book's critical and financial success and, therefore, requested a sequel. As Tolkien's work progressed on the 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.
