We examined the use of the Dewey Decimal System in a K-8 library, with the goal of increasing circulation of nonfiction materials. We provided our sponsor with an organizational framework she will use to reorganize the nonfiction section, as well as illustrated section signage and themed book kits. Our project proved that rethinking Dewey is a worthwhile endeavor, and encouraged Open Window School students to be part of the process of reimagining their library space.
