Ultimately, the most successful books will be the ones that present the material in a way that resonates with the largest number of readers.
For example, Mama: A True Story, in Which a Baby Hippo Loses His Mama During a Tsunami, but Finds a New Home, and a New Mama by Jeanette Winters is a nearly wordless picture book with compelling art. A Mama for Owen tells the same story in the form of a more traditional picture book with soft watercolor illustrations. Both are lovely books.
But it was the photo-essay approach of Owen & Mzee: The True Story of a Remarkable Friendship by Isabella Hatkoff, Craig Hatkoff, and Dr. Paula Kahumbu that truly captured the hearts of readers. It was a New York Times bestseller and spawned a whole series of photo-illustrated stories about remarkable animals.
Of course, this charming story of the tortoise and hippo isn’t the only true tale that has intrigued more than one author.

This diversity in approaches to the same nonfiction topic shows that there is no single right way to present ideas, information, or true stories to children. And that is why nonfiction authors are now experimenting with structure and design more than ever before.
