The Tin Woodman, better known as either the Tin Man or (incorrectly) the Tin Woodsman (the third name appears only in adaptations, the first—and in rare instances, the second—was used by Baum), is a character in the fictional Land of Oz created by American author L. Frank Baum.
 Baum's Tin Woodman first appeared in his classic 1900 book "The Wonderful Wizard of Oz", and reappeared in many other Oz books.
 In late 19th-century America, men made out of various tin pieces were used in advertising and political cartoons.
 Baum, who was editing a magazine on decorating shop windows when he wrote "The Wonderful Wizard of Oz", was reportedly inspired to invent the Tin Woodman by a figure he had built out of metal parts for a shop display.
The Wonderful Wizard of Oz is a 1910 American silent fantasy film and the earliest surviving film version of L. Frank Baum's 1900 novel "The Wonderful Wizard of Oz", made by the Selig Polyscope Company without Baum's direct input.
 It was created to fulfill a contractual obligation associated with Baum's personal bankruptcy caused by "The Fairylogue and Radio-Plays", from which it was once thought to have been derived.
 It was partly based on the 1902 stage musical "The Wizard of Oz", though much of the film deals with the Wicked Witch of the West, who does not appear in the musical.
Nathaniel D. Mann was an American composer best known for his work with L. Frank Baum.
 He composed at least two songs with Baum, "Different Ways of Making Love" and "It Happens Ev'ry Day," and another with John Slavin, "She Didn't Really Mind the Thing at All," for "The Wizard of Oz" stage musical in 1902, and in 1908, composed the first original film score (27 cues) for "The Fairylogue and Radio-Plays", one of the earliest feature-length fiction films (and the earliest film adaptations of the novels "The Wonderful Wizard of Oz", "The Marvelous Land of Oz", "Ozma of Oz", "John Dough and the Cherub", and "Dorothy and the Wizard in Oz", presented by Baum himself), which debuted September 24, 1908.
 With Baum, he also composed the musical "The King of Gee-Whiz" (dated February 23, 1905), which went through various titles such as "Montezuma" (November 1902), "King Jonah XIII" (September 1903), and "The Son of the Sun" (1905).
 This was collaboration with and based on a novel by Emerson Hough, which was never completed and the extant scenario published in 1969.
The Oz books form a book series that begins with "The Wonderful Wizard of Oz" (1900) and relate the fictional history of the Land of Oz.
 Oz was created by author L. Frank Baum, who went on to write fourteen full-length Oz books.
 All of the Baum written books are in the public domain in the United States.
 Even while he was alive, Baum was styled as "the Royal Historian of Oz" to emphasize the concept that Oz is an actual place.
 The illusion created was that characters such as Dorothy and Princess Ozma related their adventures in Oz to Baum themselves, by means of wireless telegraph.
Dorothy and the Wizard in Oz is the fourth book set in the Land of Oz written by L. Frank Baum and illustrated by John R. Neill.
 It was published on June 18, 1908 and reunites Dorothy with the humbug Wizard from "The Wonderful Wizard of Oz" (1900).
 This is one of only two of the original fourteen Oz books (the other being "The Emerald City of Oz" (1910), to be illustrated with watercolor paintings.
The Winkie Country is the Western region of the fictional Land of Oz in L. Frank Baum's classic series of Oz books, first introduced in "The Wonderful Wizard of Oz" (1900).
 The Winkie Country is in the West, noted by later being ruled by the Wicked Witch of the West.
 This quadrant is strictly distinguished by the color yellow.
 This color is worn by most of the native inhabitants called the Winkies and predominates in the local surroundings.
 The Winkies are relatively normal in appearance with the exception of their yellow-tinted skin.
 Tin abounds there and it is said that the Winkies are some of the most skillful tinsmiths in the world.
 This was the country once ruled by the malevolent Wicked Witch of the West before Dorothy Gale "melted" her with a bucket of water, as narrated in "The Wonderful Wizard of Oz".
 After that, the Winkies asked the Tin Woodman to be their new monarch ruler which he gladly accepted.
 He now lives in a vast palace made of tin that his loyal subjects built in his honor as a present for their new tin King.
Return to Oz is a 1985 fantasy adventure film directed and written by Walter Murch, an editor and sound designer, co-written by Gill Dennis and produced by Paul Maslansky.
 It stars Nicol Williamson as the Nome King, Jean Marsh as Princess Mombi, Piper Laurie as Aunt Em, Matt Clark as Uncle Henry and introduces Fairuza Balk as Dorothy Gale.
 It is loosely based on L. Frank Baum's "Oz" novels, mainly "The Marvelous Land of Oz" (1904) and "Ozma of Oz" (1907), yet is set six months after the events of the first novel, "The Wonderful Wizard of Oz" (1900) took place.
 Although it is not a sequel and unrelated to the 1939 Metro-Goldwyn-Mayer film, "The Wizard of Oz", it borrows a few elements of it such as the ruby slippers.
Wicked: The Untold Story of the Witches of Oz is a Broadway musical with music and lyrics by Stephen Schwartz and book by Winnie Holzman.
 It is based on the 1995 Gregory Maguire novel "", an alternative telling of the 1939 film "The Wizard of Oz" and L. Frank Baum's classic 1900 story, "The Wonderful Wizard of Oz".
 The musical is told from the perspective of the witches of the Land of Oz; its plot begins before and continues after Dorothy's arrival in Oz from Kansas, and it includes several references to the 1939 film and Baum's novel.
 "Wicked" tells the story of two unlikely friends, Elphaba (the Wicked Witch of the West) and Galinda (whose name later changes to Glinda the Good Witch), who struggle through opposing personalities and viewpoints, rivalry over the same love-interest, reactions to the Wizard's corrupt government and, ultimately, Elphaba's public fall from grace.
Dorothy Gale is a fictional character created by L. Frank Baum as the main protagonist in many of his "Oz" novels.
 She first appears in Baum's classic children's novel "The Wonderful Wizard of Oz" (1900) and reappears in most of its sequels.
 In addition, she is the main character in various adaptations, notably the classic 1939 film adaptation of the novel, "The Wizard of Oz".
The Wiz: The Super Soul Musical "Wonderful Wizard of Oz" is a musical with music and lyrics by Charlie Smalls (and others) and book by William F. Brown.
 It is an urbanized retelling of L. Frank Baum's classic 1900 children's novel "The Wonderful Wizard of Oz" in the context of modern African-American culture.
 It opened on October 21, 1974 at the Morris A. Mechanic Theatre in Baltimore, Maryland and moved to the Majestic Theatre with a new cast on January 5, 1975.
