Writings are arranged in subseries alphabetically by book title: Alberic the Wise and Other Journeys (1965), a grouping of three fantastical stories in a medieval setting; As: A Surfeit of Similes (1989), an exploration of the simile in a rhyming narrative; The Dot and the Line: A Romance in Lower Mathematics (1963), a small picture book containing the tale of a line who falls in love with a dot (adapted into an Academy Award winning animated short film in 1965); The Hello, Goodbye Window (2005), the story of the special relationship between grandparents and grandchildren, told from the perspective of a little girl and her magical getaway at her grandparent's house; Otter Nonsense (1982), issued in two different editions, a collection of puns on animal names; The Phantom Tollbooth (1961), Juster's most acclaimed piece, about young Milo's adventures in The Lands Beyond (adapted into an animated full-length feature film in 1970, as well as, by Juster himself, a libretto for an opera production in 1995); and Stark Naked (1969), another small-format book set up as a register of the citizens of the town of Emotional Heights, all of whom have names that match either their jobs or their characters.
