After L. Frank Baum died in 1919, the Oz series continued through dozens of books by other authors. Ruth Plumly Thompson wrote the most, producing nineteen novels between 1921 and 1939, starting with The Royal Book of Oz. Thompson kept Baum’s tone and created new characters like Kabumpo the elephant and Captain Salt the pirate, expanding the geography and cast of the Land of Oz considerably.
Following Thompson, other authors took turns adding to the series. Jack Snow wrote The Magical Mimics in Oz (1946) and The Shaggy Man of Oz (1949). Rachel Cosgrove Paige contributed The Hidden Valley of Oz. Eloise Jarvis McGraw and her daughter Lauren wrote Merry Go Round in Oz (1963). More recent additions include The Emerald Wand of Oz (2005) and Trouble Under Oz (2006) by Sherwood Smith, and Sky Pyrates Over Oz (2014). In total, the Oz Continued series spans nearly a century, making it one of the longest-running shared-world fantasy series in American literature.
