Ozma of Oz: A Record of Her Adventures with Dorothy Gale of Kansas, the Yellow Hen, the Scarecrow, the Tin Woodman, Tiktok, the Cowardly Lion and the Hungry Tiger; Besides Other Good People too Numerous to Mention Faithfully Recorded Herein published on July 30, 1907, was the third book of L. Frank Baum's Oz series. It was the first in which Baum was clearly intending a series of Oz books. It is the first Oz book where the majority of the action takes place outside of the Land of Oz. Only the final two chapters take place in Oz itself. This reflects a subtle change in theme: in the first book, Oz is the dangerous land through which Dorothy must win her way back to Kansas; in the third, Oz is the end and aim of the book. Dorothy's desire to return home is not as desperate as in the first book, and it is her uncle's need for her rather than hers for him that makes her return. OZ #4.
