The Economic Impact of Libraries, part of the CLA 2014 workshop, “Driving Change for Community Impact”. Presented by Kimberly Silk, University of Toronto and Elizabeth Glass, Toronto Public Library. Silk begins with a look at different types of impact studies and then introduces how the Toronto Public Library engaged the Martin Prosperity Institute at the University of Toronto in 2013 to study of the economic impact and benefits of the library in its community. TPL shares the findings of the study, discusses the importance of demonstrating the economic benefits of public libraries to key stakeholders including city councils, library board members, and the local community, and provides tips for others wanting to show the impact of their libraries.
