About Us

The Sun Prairie Public Library Foundation is based on a shared belief that the library provides a safe and inviting place for community members of all ages to enjoy lifelong learning.  

It was founded in 1999 to manage donations and create an endowment for the Library.  These funds allow the library to go above and beyond its City funding to achieve exceptional levels of service, programming, and technology for the community.

The Foundation is a 501(c)(3) not-for-profit organization and operates independently of any government oversight. It is governed by articles of incorporation, by-laws, and an investment policy for the endowment.

The Sun Prairie Public Library Foundation does not and shall not discriminate on the basis of race, color, religion (creed), gender, gender expression, national origin (ancestry), disability, marital status, sexual orientation, or military status, in any of its activities or operations. These activities include, but are not limited to, the selection of volunteers and vendors and provision of services. We are committed to providing an inclusive and welcoming environment for all members, volunteers, participants, subcontractors, and vendors. 

Please explore our site to learn more about who we are and how you can be a part of helping the library achieve new levels of excellence.
