The Columbus Academy is served by three libraries: the Reinberger Lower School Library, in the Walter Family Education Center, enhances curriculum in Pre-Kindergarten to grade 4; the Reinberger Middle School Library, located in the McCoy Learning Center, promotes academics in grades 5-8; and the Reinberger Upper School Library, located in Academy Hall, enriches the grade 9 -12 curriculum.

Supporting The Columbus Academy's tradition of academic excellence, Reinberger Libraries provide extensive print and electronic resources to foster intellectual curiosity, to inspire lifelong reading and learning, and to encourage creativity.
