The System Board is composed of one representative from each participating library and the County appointee from each participating county. They adopt the annual budget and plan of services, approve officers, and amend the bylaws. The System Board meets once a year, on the second Wednesday in August.

The County Appointees are appointed by and serve at the pleasure of the local County Commissions. One County Appointee is appointed for each member county. County Appointees serve on the System Board, and at least one County Appointee serves on the Executive Committee.

The Executive Committee consists of one member from each county in the System that levies the System tax. The Executive Committee meets monthly and is empowered to conduct all affairs of the System not reserved for the System Board.
