The school has two libraries, one in the Montessori Primary and one in the Senior school, stocked with over 4 Lakh titles that cover fiction and non-fiction in all genres and subjects. In addition, the library contains a stock of multimedia materials for use in the classes.

KNMS believes in inculcating a strong reading habit in its children. Students are actively encouraged to use the library for independent study and for research towards their presentations and projects.
