Section 75 ILCS 16/10-15 - Conversion by library board resolution and approval of corporate authorities(a) The board of trustees of a tax supported public library desiring to convert the existing library to a library maintained and operated under this Act may, rather than utilizing the procedures prescribed in Section 10-5, adopt a resolution calling for the conversion and requesting the approval of the conversion by the corporate authorities of the municipality, county, or township maintaining the existing library. If the corporate authorities approve the conversion within 60 days after the resolution is adopted by the board of trustees, the board of trustees shall convert the public library to a public library district.(b) Any library in a home rule unit, as defined in Article VII, Section 6, of the Illinois Constitution, converted under this Section shall have a maximum tax rate not to exceed the greater of 0.15% or the last rate levied by the municipality for library purposes for the most recent year before the conversion, and that rate shall not be subject to any rate limitations or referendum requirements imposed by this Act. That rate may thereafter be increased, however, as provided in Section 35-10.
