The Wonderful Wizard of Oz is a 1900 children's novel written by author L. Frank Baum and illustrated by W. W. Denslow. It is the first novel in the Oz series of books. A Kansas farm girl named Dorothy ends up in the magical Land of Oz after she and her pet dog Toto are swept away from their home by a cyclone. Upon her arrival in the magical world of Oz, she learns she cannot return home until she has destroyed the Wicked Witch of the West.
The book was first published in the United States in September 1900 by the George M. Hill Company. It had sold three million copies by the time it entered the public domain in 1956. It was often reprinted under the title The Wizard of Oz, which is the title of the successful 1902 Broadway musical adaptation as well as the 1939 live-action film.
