Charleston Community Unit School District 1: Charleston Community Unit School District 1 is a unified school district based in Charleston, the county seat of Coles County, Illinois; it was created through the consolidation of the charter school district it was formed from and over sixty-seven other school districts in the area.  Charleston Community Unit School District 1 is a conglomerate of six schools, with all but one located in Charleston itself: four elementary schools, one middle school, and one high school form the makeup of the district.  Education begins at a prekindergarten level, and those living in the Charleston area attend Mark Twain Elementary School, which prepares early youth for schooling by taking them through prekindergarten and kindergarten under the supervision of principal Terry Diss.  Students who live in the far east reaches of Coles County may attend Ashmore Elementary School, which is based in a northeasterly village by the same name; Ashmore's distance from the other schools permits it to educate a larger range of students for the sake of efficiency.  The school educates students from kindergarten through grade four, and also runs a prekindergarten program.  Ashmore is also governed by Terry Diss.  Students who graduate from Mark Twain move onwards to Carl Sandburg Elementary School, which educates those in grades one, two, and three under principal Chad Burgett.  At Jefferson Elementary School in Charleston, the student bodies from both Carl Sandburg Elementary School and Ashmore Elementary School are consolidated.  Students from grades four through six are taught in the facility under the supervision of principal Deborah Poffinbarger.  District students graduating from Jefferson are moved to Charleston Middle School, where they are taught as seventh and eighth graders; the school principal here is Sandy Wilson.  The last branch of education that Charleston's school district can provide is the education of adolescents in the grades nine through twelve at Charleston High School, which is run by principal Trevor Doughty.

Rootabaga Stories: Rootabaga Stories (1922) is a children's book of interrelated short stories by Carl Sandburg.  The whimsical, sometimes melancholy stories, which often use nonsense language, were originally created for his own daughters.  Sandburg had three daughters, Margaret, Janet and Helga, whom he nicknamed "Spink", "Skabootch" and "Swipes" -those nicknames occur in some of his Rootabaga stories.  The "Rootabaga" stories were born of Sandburg's desire for "American fairy tales" to match American childhood.  He felt that the European stories involving royalty and knights were inappropriate, and so set his stories in a fictionalized American Midwest called "the Rootabaga country" filled with farms, trains, and corn fairies.  A large number of the stories are told by the Potato Face Blind Man, an old minstrel of the Village of Liver-and-Onions who hangs out in front of the local post office.  His impossibly acquired firsthand knowledge of the stories adds to the book's narrative feel and fantastical nature.  In the Preface of the little-known "Potato Face," Sandburg wrote,

Carl Sandburg: Carl Sandburg (January 6, 1878 – July 22, 1967) was an American poet, writer, and editor.  He won three Pulitzer Prizes: two for his poetry and one for his biography of Abraham Lincoln.  During his lifetime, Sandburg was widely regarded as "a major figure in contemporary literature", especially for volumes of his collected verse, including "Chicago Poems" (1916), "Cornhuskers" (1918), and "Smoke and Steel" (1920).  He enjoyed "unrivaled appeal as a poet in his day, perhaps because the breadth of his experiences connected him with so many strands of American life", and at his death in 1967, President Lyndon B. Johnson observed that "Carl Sandburg was more than the voice of America, more than the poet of its strength and genius.  He was America."
