Oz

The Oz series is a once-popular children's book series which has attracted a significant fan base. It began with L. Frank Baum's The Wonderful Wizard of Oz, published 1900. Baum did not intend to start a series; however, readers enjoyed it so much that they called for a sequel. 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.

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.
