Standards for Selecting Materials for Classroom Collections and School Libraries An Addendum to the NYC PS Collection Development PolicyAn Addendum to the NYC PS Collection Development Policy. The books and materials students are exposed to in and outside of school help students develop a sense of identity and self, while developing a balanced perspective of the world around them. The quality and quantity of texts impacts their learning, personal growth, and development. Schools selecting materials for school libraries and classroom collections should be cognizant of the mission of the school, community, inclusiveness, quality of literature, own voices, and representation fostering the ability for students to embrace their identities and to learn to respect others. A balanced collection should also provide equitable access to physical and intellectual information that is readily available, discoverable, includes multiple perspectives, and opposing viewpoints.
