 Adams won the 1972 Carnegie Medal from the Library Association, recognising the year's best children's book by a British subject. He also won the annual Guardian Children's Fiction Prize, a similar award that authors may not win twice. In 1977 California schoolchildren selected it for the inaugural California Young Reader Medal in the Young Adult category, which annually honours one book from the last four years. In The Big Read, a 2003 survey of the British public, it was voted the forty-second greatest book of all time.
