The Caldecott Medal is an annual award given to the most distinguished American picture book for children. Established in 1938, it honors the best illustrations in children's literature, recognizing the artistic talent of illustrators. The award is named after the British illustrator Randolph Caldecott, whose work greatly influenced the genre. The Caldecott Medal is awarded by the American Library Association (ALA) and is presented during the ALA's Midwinter Meeting. Winning books are selected based on their visual storytelling, creativity, and ability to engage young readers. The medal is a prestigious honor that helps guide parents and educators in choosing quality children's books.
