"Making Visible the Invisible" Dewey Data Research


"Making Visible the Invisible" is a data analysis project at the Seattle Public Library active from 2005 to 2014. During this period, the circulation of books and media leaving the library are analyzed and visually mapped on an hourly basis. Visualizing the statistical information about what titles and topics are circulating provides a real-time living picture of the community in which the library is situated. (Project Description)
