We have asked many children how they subdivide comic books. A thirteen-year-old boy, in a letter to a national magazine commenting on one of Sterling North's excellent articles on the subject, named five groups of harmful comics: "Fantasy comics, crime comics, superman or superwoman comics, jungle comics (the worst, in my opinion) and comics which still pretend to be funny but throw in a lot of nudity to help them sell."
Many children have a simpler classification. They distinguish between "jokey" books and "interesting books." The latter they also call "exciting books" or "danger books." Very young children who supposedly read only harmless animal comic books often see others in the hands of their older siblings or in other places.
