As children grow from infancy to adolescence, they will notice that the books targeted
for them have increasingly fewer illustrations. Books for very young children
are primarily illustrations with little or no text (picture books). As children develop,
books made for them have illustrations that convey part of the message, but the text
is needed for the complete story line (picture storybooks). As they begin to read independently,
their books have illustrations that add to the story, but there are fewer of
them, and the text itself could stand alone. These books are called illustrated books .
Though the illustrations depict what is happening in the story, they do not provide
new information. The text is clearly more important than the illustrations.
