I'm not entirely sure what this is supposed to mean. Like... yes? But my point was, a school may have a very wide range of age groups. A K-12 school will have students from ages ~4 to ~18. Even a regular primary school will have 7 year olds along with 14 year olds. Point being, a book that is inappropriate for the younger students at a school may not be for the older students; and I don't see why the older students shouldn't have access to those books.
