Children's literature as such probably started in the 17th century; it is generally believed that before then books were written mainly for adults.... Additionally, most printed works were hard to come by due to their cost and were mostly available for purchase only by upper class society. Scholarship on children's literature includes professional organizations, dedicated publications and university courses. There is some debate on what constitutes children's literature. The United Nations Convention on the Rights of the Child defines a child as "a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier". Some books written for children, such as The Young Visiters by Daisy Ashford or the juvenilia of Jane Austen, written to amuse brothers and sisters, are also written by children. Anne Frank wrote a novel and many very short stories in addition to her diary . Barbara Newhall Follett wrote four books, beginning with a novel called The House Without Windows at the age of nine; when the manuscript was destroyed in a fire, she rewrote it from memory.

Fiction is the form of any narrative or informative work that deals, in part or in whole, with information or events that are not factual, but... rather, imaginary—that is, invented by the author. Although fiction describes a major branch of literary work, it may also refer to theatrical, cinematic or musical work. Fiction contrasts with non-fiction, which deals exclusively with factual events, descriptions, observations, etc. . Realistic fiction, although untrue, could actually happen. Some events, people, and places may even be real. This is termed "faction". It can be possible that in the future imagined events could physically happen. For example, Jules Verne's novel From The Earth To The Moon, which at that time was just a product of his rich imagination, was proven possible in 1969, when Neil Armstrong and Buzz Aldrin set foot on the Moon, and the team returned safely to Earth. Realistic fiction strives to make the reader feel as if they're reading something that is actually happening—something that though not real, is described in a believable way that helps the reader make a picture as if it were an actual event.

Speculative fiction is an umbrella term encompassing the more fantastical fiction genres, specifically science fiction, fantasy, horror, supernatural... fiction, superhero fiction, utopian and dystopian fiction, apocalyptic and post-apocalyptic fiction, and alternate history in literature as well as related static, motion, and virtual arts. Speculative fiction as a category ranges from ancient works to both cutting edge, paradigm-changing and neotraditional works of the 21st century. Speculative fiction can be recognized in works whose authors' intentions or the social contexts of the versions of stories they portrayed is now known, since ancient Greek dramatists such as Euripides whose play Medea seems to have offended Athenian audiences when he fictionally speculated that shamaness Medea killed her own children instead of their being killed by other Corinthians after her departure, and whose Hippolytus, narratively introduced by Aphrodite, Goddess of Love in person, is suspected to have displeased his contemporary audiences because he portrayed Phaedra as too lusty.
