The Aberdeen Library Foundation promotes the growth and development of the library, ensuring it can provide literary services and resources to the community. They support the library's welfare, public relations, and expansion of holdings. The foundation applies for technology grants to enhance children's programs and purchases educational materials. They successfully raised $2.1 million for a new library building in 2016 and now make annual contributions to the city of Aberdeen, who owns the library. In 2021, they funded streaming services to continue providing free services during the COVID-19 pandemic.
