In all cities having a population by the official state census of more than one hundred twenty thousand (120,000) and less than one hundred fifty thousand (150,000) in which a free public library has heretofore been established as provided by law, the board of directors of such free public library is hereby authorized and empowered to submit the question of making an annual tax levy of not to exceed one (1) mill for a period not to exceed five (5) years upon the taxable tangible property within such city for the purpose of creating a building fund to be used for the construction, reconstruction, additions to, furnishing and equipping of the building housing such free public library and of a building to house motor vehicles of such free public library and the architectural expense incidental thereto, to the electors of such city at an election called and held in the manner provided for the calling and holding of elections under the provisions of the general bond law, at the time fixed for the holding of the primary election in August. The amount of such levy and the period for which it will be made shall be stated in the notice and upon the ballot of such election. No tax levy shall be made under the provisions of this act without the question of the making of such levy having been submitted to and having received the approval of a majority of the electors of such city voting thereon at an election called and held for such purpose. All moneys derived from the tax levy authorized by this act shall be placed in a building fund to be used only for the purposes for which the tax levy was made. All tax levies authorized by this act shall be in addition to all other tax levies authorized by law and shall not be subject to any of the limitations prescribed by law, including Kan. Stat. Ann. §§ 12-1215 and 12-1217 and any acts amendatory thereof or supplemental thereto.
