The Nine Peahens and the Golden Apples ("Zlatna jabuka i devet paunica") is a Serbian epic poetry.
 It was published for the first time as a fairy tale by Vuk Stefanović Karadžić in 1853.
 Later on it was published as a Bulgarian fairy tale by A. H. Wratislaw in his "Sixty Folk-Tales from Exclusively Slavonic Sources", number 38 in 1890.
 Andrew Lang included it in "The Violet Fairy Book", as a translation from a German version of Karadžić's original tale.
 Ruth Manning-Sanders included it in "".
 It is Aarne-Thompson type 400*, the swan maiden.
Howard Elliott Ashman (May 17, 1950 – March 14, 1991) was an American playwright and lyricist.
 He collaborated with Alan Menken on several works and is most widely known for several animated feature films for Disney, for which Ashman wrote the lyrics and Menken composed the music.
 Ashman and Menken began their collaboration with the musical "God Bless You, Mr. Rosewater" (1979), for which Ashman directed and wrote both book and lyrics.
 Their next musical, "Little Shop of Horrors" (1982) for which Ashman again directed and wrote both book and lyrics, became a long-running success and led to a 1986 feature film.
 The partnership's first Disney film was "The Little Mermaid" (1989), followed by "Beauty and the Beast" (1991).
 After his death, some of Ashman's songs were included in another Disney film, "Aladdin" (1992).
The Buried Moon or The Dead Moon is a fairy tale included by Joseph Jacobs in "More English Fairy Tales".
 It is a striking unusual tale, with few variants, and often appearing more mythological than is common for fairy tales.
 It was collected by Mrs. Balfour from the North Lincolnshire Carrs in the Ancholme Valley; its unusual characteristics made many people doubt its origins as a fairy tale.
 However, when Mrs. Balfour published her notes, they were generally found reliable, and the Fens proved to have many other unusual legends.
 The story may be evidence of moon worship.

Stan Bolovan is a Romanian fairy tale collected in "Rumänische Märchen" by Mite Kremnitz (1882).
 Fairy tale collector Andrew Lang included it in his "The Violet Fairy Book" (1901).

New Fairy Tales (Danish: "Nye Eventyr" ) is a collection of four fairy tales written by Hans Christian Andersen and published by C. A. Reitzel in Copenhagen, Denmark on 10 November 1843.
 As was customary at the time however, the title page is dated 1844.
 The tales are completely Andersen's invention, owe no debt to folk or fairy lore, and are the most autobiographical of his several fairy tale collections.
 The collection was received enthusiastically by the Danish critics and public and became Andersen's break-through in the fairy tale genre.
 "The Nightingale" and "The Ugly Duckling" have been adapted to various forms of drama.
Kashchey the Deathless (Russian: Кащей бессмертный , "Kashchey bessmertnïy"), Kashchey the Immortal, is a one-act opera in three scenes (styled a "little autumnal fairy tale") by Nikolai Rimsky-Korsakov.

 A similar fairy tale was also used by Igor Stravinsky (Rimsky-Korsakov's pupil) and Michel Fokine to create their iconic ballet, "The Firebird".
