Context paragraphs:
Jack Snow (writer): John Frederick "Jack" Snow (August 15, 1907 – July 13, 1956), born Piqua, Ohio was an American radio writer, writer of ghost stories, and scholar, primarily of the works of L. Frank Baum.  When Baum died in 1919, the twelve-year-old Snow offered to be the next Royal Historian of Oz, but was politely turned down by a staffer at Baum's publisher, Reilly & Lee.  Snow eventually wrote two Oz books: "The Magical Mimics in Oz" (1946) and "The Shaggy Man of Oz" (1949), as well as "Who's Who in Oz" (1954), a thorough guide to the Oz characters, all of which Reilly & Lee published.

The Dreamer of Oz: The L. Frank Baum Story: The Dreamer of Oz: The L. Frank Baum Story is a 1990 made-for-television biographical film starring John Ritter as Lyman Frank Baum, the man who wrote "The Wonderful Wizard of Oz" and thirteen of the other Oz books.  Also starring in this TV movie was Annette O'Toole as Baum's supportive wife, Maud, and Rue McClanahan as Baum's tough mother-in-law, Matilda Gage.  John's son, Jason Ritter, makes his debut in this telefilm as Harry Neal Baum.  At the time of the film's debut, O'Toole and Ritter also starred in "It", a TV miniseries where they played a couple.

Plays of L. Frank Baum: The plays of L. Frank Baum are an important aspect of Baum's writing career about which some of the least is known.  While even most brief biographies, long before the Internet, have noted Baum's work as a playwright, these works have been rarely performed beyond his lifetime, and almost none have been published aside from two scenarios and a first act of three unfinished works in "The Musical Fantasies of L. Frank Baum", compiled with an introduction by Alla T. Ford.  Aside from his youthful success with "The Maid of Arran", his blockbuster eight-year run with "The Wizard of Oz", his failure with "The Woggle-Bug", and "The Tik-Tok Man of Oz" as source material for his novel, "Tik-Tok of Oz", very little is known about his dramatic output, and mostly from the publications of Michael Patrick Hearn, Susan Ferrara, and Katharine M. Rogers.  Hearn identifies 41 different titles in the bibliography of the 2000 edition of "The Annotated Wizard of Oz", plus one play without a title, although some of these titles clearly refer to drafts of the same play, such as the early titles of "The Tik-Tok Man of Oz".

Roger S. Baum: Roger Stanton Baum (born 1938) is a former banker and stockbroker, and currently (as of 2005) a children's author, residing in Las Vegas.  Baum publishes under the name Roger S. Baum.  Baum is a former resident of Los Angeles.  He also tours the country, reading from and signing his children's books.  Baum is a great-grandson of L. Frank Baum, the original creator of the "Oz" series, and grandson of Frank Joslyn Baum, who published "The Laughing Dragon of Oz" in 1935.  Many of Roger S. Baum's children's books are set in the same world.

The Royal Book of Oz: The Royal Book of Oz (1921) is the fifteenth in the series of Oz books, and the first by Ruth Plumly Thompson, to be written after L. Frank Baum's death.  Although Baum was credited as the author, it was written entirely by Thompson.  Beginning in the 1980s, some editions have correctly credited Thompson, although the cover of the 2001 edition by Dover Publications credits only Baum.  The original introduction claimed that the book was based on notes by Baum, but this has been disproved.  Baum's surviving notes, known as "An Oz Book" are known from four typewritten pages found at his publisher's, but their authenticity as Baum's work has been disputed.  Even if genuine, they bear no resemblance to Thompson's book.

Nathaniel D. Mann: 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.

Rue McClanahan: Eddi-Rue McClanahan (February 21, 1934 – June 3, 2010) was an American actress and comedienne best known for her roles on television as Vivian Harmon on "Maude" (1972–78), "Aunt" Fran Crowley on "Mama's Family" (1983–84), and Blanche Devereaux on "The Golden Girls" (1985–92), for which she won an Emmy Award for Outstanding Lead Actress in a Comedy Series in 1987.

List of Oz books: 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.

The Wizard of Oz (1933 film): The Wizard of Oz (1933) is a Canadian animated short film directed by Ted Eshbaugh.  The story is credited to "Col. Frank Baum."  Frank Joslyn Baum, a Lieutenant Colonel in the United States Army and eldest son of writer L. Frank Baum, was involved in the film's production, and may have had an involvement in the film's script, which is loosely inspired by the elder Baum's novel, "The Wonderful Wizard of Oz".  It runs approximately eight and a half minutes and is nearly absent of language, working mainly with arrangements of classical music created by Carl W. Stalling.

L. Frank Baum's Juvenile Speaker: L. Frank Baum's Juvenile Speaker: Readings and Recitations in Prose and Verse, Humorous and Otherwise is an anthology of literary works by L. Frank Baum, author of the Oz books.  The book was first published in 1910, with illustrations by veteran Baum artists John R. Neill and Maginel Wright Enright; a subsequent 1912 edition was retitled Baum's Own Book for Children.  The book constitutes a complex element in the Baum bibliography.
