Children's literature or juvenile literature includes stories, books, magazines, and poems that are created for children. In addition to conventional literary genres, modern children's literature is classified by the intended age of the reader, ranging from picture books for the very young to young adult fiction for those nearing maturity.
Children's literature can be traced to traditional stories like fairy tales, which have only been identified as children's literature since the eighteenth century, and songs, part of a wider oral tradition, which adults shared with children before publishing existed. The development of early children's literature, before printing was invented, is difficult to trace. Even after printing became widespread, many classic "children's" tales were originally created for adults and later adapted for a younger audience. Since the fifteenth century much literature has been aimed specifically at children, often with a moral or religious message. Children's literature has been shaped by religious sources, like Puritan traditions, or by more philosophical and scientific standpoints with the influences of Charles Darwin and John Locke. The late nineteenth and early twentieth centuries are known as the "Golden Age of Children's Literature" because many classic children's books were published then.
