About Libraries

How are Public Libraries funded?

The vast majority of funding that supports the operation of Public Libraries comes from county and local governments. At times, grant funding may be available for specific programs, projects, or capital improvements. Fees for special programs and services account for a relatively small percentage of revenue for Public Libraries.

What are the Friends of the Library?

Friends of the Library are organizations formed to support their local Public Libraries. They typically establish themselves as independent, non-profit organizations that conduct fundraising to supplement Library resources and organize Library related events.

What is the Dewey Decimal system?

The Dewey Decimal system is a classification system used in many libraries to organize their books. The classification number allows for books to easily be located or returned to their assigned place in the library. The system is constantly revised to keep up with changes in the libraries.
