Many of Brown's books have been re-issued with new illustrations decades after their original publication. Many more of her books are still in print with the original illustrations. Her books have been translated into several languages; biographies on Brown for children have been written by Leonard S. Marcus (Harper Paperbacks, 1999), Jill C. Wheeler (Checkerboard Books, 2006), and Amy Gary (Flatiron Books, 2017). There is a Freudian analysis of her "classic series" of bunny books by Claudia H. Pearson, "Have a Carrot" (Look Again Press, 2010).
