"Metis is a flexible, intuitive and child-friendly system of library categorization. It uses whole language, visual cues, and logic that reflects children's own experiences. It puts the child in the center of his or her own search. Our decision to create Metis is a result of our progressive approach to education and the library. The system isn't a cut-down version of adult thinking. Kids feel empowered to navigate the library because it is organized in a way that they understand. Metis increases the success rate of finding books, which fosters self-reliance and produces joyous discovery. We have named the system in honor of the crafty Titan who is the mother of Athena and the eternal source of good advice for Zeus."
