The Friends of Springfield Town Library (FOSTL) was organized as a Vermont non-profit corporation in 1989 to support the Library. It focuses public attention on the Library, encourages the use of its resources and services, provides additional resources and services not funded through tax support, and encourages and receives gifts and bequests to benefit the Library.

Membership is open to everyone interested in supporting the Library. Through fundraising activities, membership dues, and donations, FOSTL is able to provide exceptional extra support for the Library every year.
