The John Newbery Medal is a literary award given by the Association for Library Service to Children of the American Library Association (ALA) to the author of the outstanding American book for children. The award has been given since 1922. Together with the Caldecott Medal, it is considered the most prestigious award for children's literature in the United States. It is named for John Newbery, an 18th century publisher of juvenile books. The Newbery Medal was designed by Rene Paul Chambellan in 1921 and depicts on the reverse, an author giving his work (a book) to a male and female child to read.
