Where did these numbers come from?
Typical taxpayer contributions are determined from the library's 2008 local income per capita. For libraries in Colorado, this can be found at http://www.lrs.org/data-tools/public-libraries/annual-statistics/. We borrowed value of library service figures from Maine State Library's Library Use Value Calculator. For more information, see their explanation.
