The Patchwork Girl of Oz by L. Frank Baum, is a children's novel, the seventh set in the Land of Oz. Characters include the Woozy, Ojo "the Unlucky," Unc Nunkie, Dr. Pipt, Scraps (the patchwork girl), and others. The book was first published on July 1, 1913. In 1914, Baum adapted the book to film through his "Oz Film Manufacturing Company." In the previous Oz book, The Emerald City of Oz, magic was used to isolate Oz from all outside worlds. Baum did this to end the Oz series, but was forced to restart the series with this book due to financial hardships. In the prologue, he explains how he managed to get another story about Oz, even though it is isolated from all other worlds. He explains that a child suggested he make contact with Oz with wireless telegraphy. Glinda, using her book that records everything that happens, is able to know that someone is using a telegraph to contact Oz, so she erects a telegraph tower and has the Shaggy Man, who knows how to make a telegraph reply, tell the story contained in this book to Baum. This story is the first one since the original The Wonderful Wizard of Oz to send its hero on a quest through the land of Oz, a technique that allowed Baum to showcase the marvels of the land. The book was dedicated to Sumner Hamilton Britton, the young son of one of its publishers, Sumner Charles Britton of Reilly & Britton.
