Lyman Frank Baum (1856-1919) was an American writer of children's books, best known for creating the marvelous Land of Oz in "The Wonderful Wizard of Oz". This fanciful kingdom was catalogued in a series of children's books beginning with the publication of "The Wonderful Wizard of Oz". Baum's Oz series signifies the first fully developed fantasy world created by an American author. In 1900, Baum and Denslow, famous illustrator with whom he shared the copyright, published "The Wonderful Wizard of Oz", making it one of the first commercially successful uses of color illustrations in American publishing. Dorothy and her friends soon began their journey toward becoming an integral part of the American consciousness. "Glinda of Oz" was Baum's last contribution to the Oz series. Like the majority of the Oz books, the plot features a journey through the remote regions of Oz in which Dorothy and Ozma travel to stop a war between the Flatheads and Skeezers. Glinda and her entourage from the Emerald City set out to rescue the duo.
