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. Beside 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. The award was named after English illustrator Randolph Caldecott. Unchanged since its founding, the medal, which is given to every winner, features two of Caldecott's illustrations. The awarding process has changed several times over the years, including in 1971 which began use of the term "Honor" for the runner-ups. There have been between one and five honor books named each year. To be eligible for a Caldecott, the book must be published in English, in the United States first, and be drawn by an American illustrator. An award committee decides on a winner in January or February, voting using a multi-round point system. The committee judges books on several criteria to meet the Caldecott's goal of recognizing "distinguished illustrations in a picture book and for excellence of pictorial presentation for children." Winning the award can lead to a substantial rise in books sold. It can also increase the prominence of illustrators. Illustrator and author Marcia Brown is the most recognized Caldecott illustrator having won three medals and having six honor books. In recent years, there has been an increase in the number of minority characters and illustrators recognized. However, this is something which has fluctuated over the history of the award.
