The short answer is...a LOT:
Your ECC Libraries receive state aid directly through the Coordinated Collection Development Assistance (CCDA) grants that our regional library advocacy council (WNYLRC) sends out to academic libraries each year. Each year, ECC receives roughly $13,000. Depending on the year, this can be the bulk of what they get to spend (for books, journal and database subscription, etc.) in a year!
And the impact of annual underfunding really adds up...see the "Cumulative Gap" bar at the right in the graph below:
