The Orange County Library Board of Trustees consists of 6 trustees appointed by the Orange County Board of Supervisors. Each serves for a 4 year term. One trustee represents each of the 5 Orange County voting districts and the sixth serves as an at-large member. The Trustees serve as volunteers and set library policies, conduct advocacy, and provide guidance and input on the library's budget. They also select and evaluate the Library Director. Trustees may also be asked to serve on evaluation committees for large purchases.  Trustees also serve as the final arbiter for any reconsideration requests that have been appealed after a completed staff review process.
