School libraries have an unique role in the world of libraries.
They exist to support learning and educational activities of the students in the school, based on curriculum chosen, designed, and instructed by the school's educators. Cooperative collection development goes beyond the borrowing and lending of physical resources among libraries. One of the best distinctions between resource sharing and cooperative collection development is that resource sharing involves the sharing of current or existing resources, whereas CCD involves the acquisition and sharing of future resources. Its goal is to maintain strong collecting priorities in the areas of heavy need and use for their own libraries. All members of the Buffalo School Library System are invited to participate.
