Ozma of Oz is the book in Frank Baum's Oz book series. It records the adventures of Oz with Dorothy Gale of Kansas, the Yellow Hen, the Scarecrow, the Tin Woodman, Tiktok, the Cowardly Lion and the Hungry Tiger; and other characters. It is the first Oz narrative in which the majority of the events occur outside of Oz. Only the final two chapters are set in Oz. This conveys a slight change in theme: in the first book, Oz is the perilous land through which Dorothy must make her way back to Kansas; in the third, Oz is the book's conclusion and goal. Dorothy's wish to return home is not as strong as it was in the first book, and it is her uncle's need for her rather than her own that compels her to do so.

The Wonderful Wizard of Oz is a children's novel written by L. Frank Baum and illustrated by W. W. Denslow. Originally published by the George M. Hill Company in Chicago on May 17, 1900, it has since been reprinted numerous times, most often under the name The Wizard of Oz, which is the name of both the popular 1902 Broadway musical and the well-known 1939 film adaptation. The story chronicles the adventures of a young girl named Dorothy Gale in the Land of Oz, after being swept away from her Kansas farm home in a cyclone.[nb 1] The novel is one of the best-known stories in American popular culture and has been widely translated. Its initial success, and the success of the 1902 Broadway musical which Baum adapted from his original story, led to Baum's writing thirteen more Oz books. The original book has been in the public domain in the US since 1956. Baum dedicated the book "to my good friend & comrade, My Wife," Maud Gage Baum. In January 1901, George M. Hill Company, the publisher, completed printing the first edition, which totaled 10,000 copies.

L. Frank Baum originally published 14 Oz books. Presented here in The Big Book of Oz, Volume 1: The Oz Series, are the first 7 books. The first one being the famous 'Wonderful Wizard of Oz.' The books are still sure to delight all ages.

On her way back from Australia, Dorothy visits her cousin, Zeb, in California. They are soon swallowed up by an earthquake, along with Zeb's horse Jim and Dorothy's cat Eureka. The group soon meets up with the Wizard and all travel underground back to Oz.

In the first of L. Frank Baum's time-honored Oz novels, country girl Dorothy Gale gets whisked away by a cyclone to the fantastical Land of Oz. Dropped into the midst of trouble when her farmhouse crushes a tyrannical sorceress, Dorothy incurs the wrath of the Wicked Witch of the West. Dorothy is desperate to return to her native Kansas, and, aided by the Good Witch of the North, she sets out for the Emerald City to get help from the legendary Wizard. On her way, she meets three unlikely allies who embody key human virtues—the Scarecrow, the Tin Woodman, and the Cowardly Lion.

Afterword by Peter Glassman. "Dorothy is called back to Oz by Glinda, the Good Witch of the South, because the Tin Woodman, the Scarecrow, and the Cowardly Lion need help....The great-grandson of L. Frank Baum here adds to the Oz canon with a story that is true to the originals....Oz fans will welcome this new adventure."--Booklist.
