The seven-member Library Board of Trustees is appointed by the Mayor at the consent of the Township Council. The Board serves to help govern the Library by advising rules and policies and approving expenditures for payment.
The Piscataway Public Library Foundation is organized exclusively for the charitable and educational purpose of supporting the operation of the Piscataway Public Library. The Foundation raises funds through events, grants, and donations from charitable foundations, local businesses, and private individuals.
The Friends of the Piscataway Public Library is a large group of volunteers who give their time. The Friends support the Library by collecting, organizing, and selling thousands of donated books each year in two annual book sales. These book sales generate substantial funds that are used to enhance the Library.
