STATE OF WISCONSIN: The State of Wisconsin provides funding to the Milwaukee County Federated Library System (MCFLS) as detailed in Wisconsin State Statutes 43.24(a-c). The State of Wisconsin, Department of Public Instruction, provides administrative oversight to the functions of MCFLS.

MILWAUKEE COUNTY GOVERNMENT: The Milwaukee County Executive appoints the seven-member MCFLS Board of Trustees. One seat on the MCFLS Board of Trustees is filled, as stipulated by state statute, by a Milwaukee County Supervisor. Milwaukee County government is the trustee of MCFLS state aid payments and provides fiscal oversight to those monies.

CITY OF MILWAUKEE: The Milwaukee Public Library (Central) serves, on a statutory and contractual basis, as the Resource Library of the Milwaukee County Federated Library System. In that capacity the Milwaukee Public Library (Central) provides a number of specialized reference and materials support services to the other fourteen MCFLS member libraries.
