Sing a song of sixpence

The Randolph Caldecott Medal, frequently shortened to just the Caldecott, annually recognizes the preceding year's "most distinguished American picture book for children". It is awarded to the illustrator by the Association for Library Service to Children (ALSC), a division of the American Library Association (ALA). The Caldecott and Newbery Medals are considered the most prestigious American children's book awards. Besides the Caldecott Medal, the committee awards a variable number of citations to runners-up they deem worthy, called the Caldecott Honor or Caldecott Honor Books. The Caldecott Medal was first proposed by Frederic G. Melcher in 1937.
