Body of written works produced to entertain or instruct young people.
The genre encompasses a wide range of works, including acknowledged classics of world literature, picture books and easy-to-read stories, and fairy tales, lullabies, fables, folk songs, and other, primarily orally transmitted, materials. It emerged as a distinct and independent form only in the second half of the 18th century and blossomed in the 19th century. In the 20th century, with the attainment of near-universal literacy in most developed nations, the diversity in children's books came almost to rival that of adult popular literature.
