1. Any consolidated public library district created under sections 182.610 to 182.670 may enlarge the area it serves by incorporating into it any county, city, municipal, school or public library district.

2. The board of trustees of a county, city, municipal, school or public library district may, by resolution duly acted upon, petition the board of trustees of a consolidated public library district to become a part of and be included in such consolidated public library district. The petitioning district may be admitted into the consolidated public library district upon majority vote of the board of trustees of the consolidated public library district at the prevailing tax rate of the consolidated district. Notice of inclusion of the petitioning district into the consolidated public library district shall be given to the governing authority of the district so included in accordance with the notice provisions set out in section 182.620.

3. Whenever five percent of the voters of a county, city, municipal, school or public library district shall petition in writing the governing authority of the district to be included in the consolidated public library district and upon written approval by majority vote of the board of trustees of the consolidated public library district, it shall be the duty of the governing authority to submit the question to the voters of the petitioning district at an election.

4. Upon admission of any petitioning district by majority vote of the board of trustees of the consolidated public library district or upon majority approval of the voters of any such district for inclusion in the consolidated public library district, the taxing authority and governing authority of the district shall take appropriate action to transfer, within sixty days following the approval or election, all title and interest in all property both real and personal in the name of the district, to the board of trustees of the consolidated public library district. Upon the transfer of the title and interest in the property, it shall become a part of the consolidated public library district, and the petitioning district and its board of trustees shall cease to exist. Notwithstanding section 182.640 to the contrary, if the petitioning district is a city or municipal library district located in part in any county that is not a county participating in the consolidated public library district, the board of trustees of the consolidated public library district shall expand to include one additional trustee appointed by the county commissioners or county executive officers of the county not currently included in the consolidated public library district. Upon the admission of the petitioning district for inclusion in the consolidated public library district, the transfer of the title and interest in property of such petitioning district, and the appointment of the additional trustee, the petitioning district and its board of trustees shall cease to exist.

5. If the tax levy for the district admitted is not at the same rate as that of the consolidated public library district or if there is no tax levied in the district for the support of public libraries, then at the beginning of the next taxing period a tax or taxes shall be levied in the district admitted to conform to and be the same as that levied in the consolidated public library district.
