The Sun Prairie Public Library Foundation has no official ties to the City of Sun Prairie other than a shared belief that the library provides a safe and inviting place for community members of all ages to enjoy lifelong learning. The Foundation is a 501(c)(3) not-for-profit organization and operates independently of any government oversight.
The Foundation currently holds more than $410,000 in assets, which are conservatively invested to generate income to be directed toward the library. In 2006, the Foundation reached their initial goal of $100,000, which allows them to give 50% of the investment income to the library every year. The Foundation strives to reach its next goal of $500,000, when it will be able to give 100% of investment income to the library each year.
The Foundation board consists of dedicated volunteers who meet bi-monthly to discuss investment, fund raising, and advocacy strategies.
