Context paragraphs:
The Runaway in Oz: The Runaway in Oz is an Oz book by long-time Oz illustrator John R. Neill.  It was written originally during 1943 and was meant to be the thirty-seventh book in the Oz series.  However, Neill died before he could edit or illustrate the book.  Oz publisher Reilly & Lee decided not to publish the book due to shortages caused by World War II.  The text remained a possession of Neill's family.

The Emerald City of Oz: The Emerald City of Oz is the sixth of L. Frank Baum's fourteen Land of Oz books.  It was also adapted into a Canadian animated film in 1987.  Originally published on July 20, 1910, it is the story of Dorothy Gale and her Uncle Henry and Aunt Em coming to live in Oz permanently.  While they are toured through the Quadling Country, the Nome King is assembling allies for an invasion of Oz.  This is the first time in the Oz series that Baum made use of double plots for one of the books.

Glinda of Oz: Glinda of Oz is the fourteenth Land of Oz book written by children's author L. Frank Baum, published on July 10, 1920.  It is the last book of the original Oz series, which was later continued by other authors.  Like most of the Oz books, the plot features a journey through some of the remoter regions of Oz; though in this case the pattern is doubled: Dorothy and Ozma travel to stop a war between the Flatheads and Skeezers; then Glinda and a cohort of Dorothy's friends set out to rescue them.  The book was dedicated to Baum's second son, Robert Stanton Baum.

Rinkitink in Oz: Rinkitink in Oz: Wherein is Recorded the Perilous Quest of Prince Inga of Pingaree and King Rinkitink in the Magical Isles that Lie Beyond the Borderland of Oz.  is the tenth book in the Land of Oz series written by L. Frank Baum.  Published on June 20, 1916, with full-color and black-and-white illustrations by artist John R. Neill, it is significant that no one from Oz appears in the book until its climax; this is due to Baum's having originally written most of the book as an original fantasy novel over ten years earlier, in 1905.  Most of the action takes place on three islands – Pingaree, Regos, and Coregos – and within the Nome King's caverns.  Since the original ruler of the nomes, Roquat – who later renamed himself Ruggedo, was deposed in 1914's "Tik-Tok of Oz", Baum had to cleverly rework the tale to accommodate his successor, the well-intentioned – but politically motivated – Kaliko.

Cap'n Bill: Cap'n Bill Weedles is a fictional character found in L. Frank Baum's Land of Oz.  Cap'n Bill and his friend Trot were introduced in Baum's fantasy novels "The Sea Fairies" (1911) and "Sky Island" (1912).  They first appear in Oz in "The Scarecrow of Oz" (1915), the ninth book in the Oz series.

The Curse of Naar: The Curse of Naar is the twentieth book in the award-winning Lone Wolf book series created by Joe Dever.  This is the final book in the "Grand Master" series, and the last one released in North America.

Animal Fairy Tales: Animal Fairy Tales is a collection of short stories written by L. Frank Baum, the creator of the Land of Oz series of children's books.  The stories (animal tales, comparable to Aesop's Fables or the "Just-So Stories" and "Jungle Book" of Rudyard Kipling) first received magazine publication in 1905.  For several decades in the twentieth century, the collection was a "lost" book by Baum; it resurfaced when the International Wizard of Oz Club published the stories in one volume in 1969.

Wish Way: A Wish Way is a device that appears in three of the Oz books of Ruth Plumly Thompson, "The Royal Book of Oz", "The Hungry Tiger of Oz", and "The Lost King of Oz".  Two Wish Ways are found in distinctly different locations, both in the Winkie Country.
