“The function of informational books is to discover facts and concepts.” (A Critical Handbook of Childrens Literature, Rebecca J. Lukens)

This is a simple definition of what an informational genre is. In the world of Literature, there is more of a difference between being a child and an adult than you might know. Children have an almost unending curiosity and they will try to satisfy this by reading many types of books. A good statement given by Rebecca J. Lukens about this concept is this: “They are filled with questions that lead to more questions that, when answered, lead to still other questions.” Adults on the other hand, use one source like an encyclopedia, to find the information they need. By using books with simplified facts, adults limit their learning experience. In most cases, they will not come across new concepts that will engage them into further research. A child on the other hand will constantly have his curiosity grow because children's informational books are written to challenge the child with new ideas and foreign concepts. This is why informational books are so important for children.
