For purposes of this section, the term "local government unit" means a home rule charter or statutory city, county, or town.
A local government unit may agree with other local government units to subject taxable property within their boundaries to taxation to discharge debt incurred for the construction of a library and related facilities. The portion of the debt to be discharged by taxation in each unit must be set by agreement. A unit may also agree to discharge a portion of the costs of construction or debt incurred for the costs by a transfer of money available to the unit that the unit is not obliged by law to use for some other purpose. A proposed agreement that has a town as a party must be approved at the town's annual meeting by the electors before the agreement is effective. Obligations for the purpose may be issued jointly by the agreeing units without an election and are not subject to the general limit on net debt in any unit. In other respects, the debt must be incurred and discharged in accordance with chapter 475.
