S.C. Code § 60-1-100
The services and resources of the South Carolina State Library and any public library receiving state and federal funds administered by the State Library are free for use by all persons living within South Carolina or the county or region served, except each public library board may fix and each public library may collect reasonable fees and service charges as the board considers necessary to offset the costs of special library services. The State Library may charge fees for the cost of on-line reference services and other nontraditional library services and retain the fees to offset the cost of the services. A board may assess fines, penalties, damages, or replacement costs for the loss of, damage to, or failure to return any library property or material. The use of a library is subject to regulations adopted by the library's board and the board may extend use of the library to nonresidents upon terms and conditions as it may prescribe.
