"Informational books are defined as those written and illustrated to present, organize, and interpret documentable, factual material." Poetry and traditional literature such as folktales are not eligible but there is no other restriction (such as reference books or even nonfiction books). The book must be published originally or simultaneously in the United States and in English.^[3]
