Resumen
Although a public agency, many libraries seek additional resources beyond municipal taxes. This paper explores library funding and their reliance on philanthropic revenue to supplement public tax dollars. Data from the Institute of Museum and Library Services Survey are combined with financial information from library friends and foundation nonprofit organizations to understand the extent to which public libraries in Illinois are supported by philanthropic funds. A survey of library directors is used to provide additional context. The findings suggest a geographic disparity in finances among libraries in Illinois and the need for new theories to explain ?donation over taxation.?
