Some authors were concerned that illustrations would date or misinterpret their prose. Henry James disliked illustrations, claiming that illustrations were not needed because prose was sufficiently pictorial. He thought that illustrations and prose were in competition with one another. He permitted his travel books, but not his mature fiction, to be illustrated. Alvin Langdon Coburn's photographs were used in the New York edition of his works only as frontispieces, and only after James reassured himself that they did not compete or make a reference to his prose. Similar to James, Thomas Hardy increasingly excluded illustrations from the collected editions of his novels, with the exception of maps that he had drawn and photographic frontispieces.
