The Marmot Council is comprised of representatives appointed by Member Libraries. The primary responsibility of the Council is to approve amendments to the Articles of Incorporation and Bylaws of the Corporation. The Council meets at least once a year, in the spring. Every few years the Council meets to create a "Strategic Plan" to guide annual decisions regarding budgets and special projects.

The Executive Board is elected by the Council to approve Marmot budgets, contracts, policies, and member fees. The Board meets at least quarterly.

The Board President may appoint Committees to carry on the business of the Corporation or to advise the Board. "Task Forces" (not explicitly mentioned in the Bylaws) may be formed from time to time to perform or oversee special projects.

The Executive Director is hired by the Board the to manage day-to-day activities of the corporation, and to supervise staff who provide services for member libraries.
