The board may contract with any public or private corporation or entity for the purpose of providing or receiving library service or of performing other acts necessary and proper to carry out the responsibilities, the intent, and the provisions of this Act. This contractual power includes, but is not limited to, (i) participating in interstate library compacts and library systems, (ii) contracting to supply library services, and (iii) spending any federal or State funds made available to any county, municipality, or township or to the State of Illinois for library purposes. If, however, a contract is for the supply of library services for residents without a public library established under this Act, the terms of that contract shall recognize the principle of equity of cost of services to non-residents expressed in this Section and shall provide for the assumption, by the contracting party receiving the services, of financial responsibility for the loss of or damage to any library materials provided to non-residents under the contract.
