Infinite Sums Grant

Grant Program Overview

Through generous funding from the Simons Foundation and in partnership with SciStarter, ARSL is offering a micro-grant program to support rural libraries in hosting community math events as part of the Infinite Sums 2026 Program. An overview of the program will be presented at the 2025 ARSL Conference.
