The latter part of the 19th century experienced an increase in the popularity of illustrated children's literature. Many of these new books were created for the pleasure of reading rather than strictly educational purposes. With the development of new technologies such as chromoxylography (a method developed for multi-color printing), illustrators such as Kate Greenaway, Arthur Rackham, and Walter Crane were able to translate their artwork into picture storybooks for children. Special Collections holds several volumes by these three authors.
