He is best known for The Snowy Day, which won the 1963 Caldecott Medal and is considered one of the most important American books of the 20th century. He wrote 22 books and illustrated at least 70 more in his signature collage art style. Keats is known for introducing multiculturalism into mainstream American children's literature. Keats' works have been translated into some 20 languages, including Japanese, French, Danish, Norwegian, Spanish, Italian, Portuguese, Turkish, German, Swedish, Thai, Chinese, and Korean.
