Oz

The Oz series is popular children's book series which has attracted a significant fan base. It began with L. Frank Baum's The Wonderful Wizard of Oz, with illustrations by W.W. Denslow, published in 1900. Baum did not intend to start a series; however, readers enjoyed it so much that they called for a sequel, and he needed the money after moving to Hollywood. While Baum tried to end the series at least twice, he ended up writing fourteen books. After his death, other authors continued the series up to 1963.

While Baum himself stated that he wrote Wizard of Oz "solely to please children of today", the Oz books have addressed or left significantly unaddressed several philosophical questions. The political themes that appeared in the original The Wizard of Oz in 1900 and the Broadway play based on it were not continued in the rest of the series. The famous 1939 movie version is based on the 1900 original.

List of official Oz books

Forty official Oz books were published by the original publishers. Fans have written and published many unofficial books; however, these mostly do not have the permission of the original authors and are mostly considered unofficial.

By Ruth Plumly Thompson

After Baum's death, his publisher (with Baum's wife's consent) hired Ruth Plumly Thompson, a popular childrens' book author, to continue the series.

Thompson's earlier books moved into the public domain before the Sonny Bono Copyright Term Extension Act; her later books are also public-domain because she neglected to renew the copyright.
