The election commissioners shall certify to the County Judge the result of the vote. The County Judge shall cause the result of the election to be entered of record in the County Court. The result so entered shall be conclusive unless attacked in the courts within thirty days. If a majority of the qualified electors voting on the question at such election vote in favor of the specified tax, then it shall thereafter be continually levied and collected as other general taxes of such county are levied and collected; provided, however, that such tax shall not be levied against any real or personal property which is taxed for the maintenance of a city library, pursuant to the provisions of Amendment No. 30; and no voter residing within such city shall be entitled to vote on the question as to whether county tax shall be levied. The proceeds of any tax voted for the maintenance of a county public library or county library service or system shall be segregated by the county officials and used only for that purpose. Such funds shall be held in the custody of the County Treasurer. No claim against said funds shall be approved by the County Court unless first approved by the County Library Board, if there is a county Library Board functioning under Act 244 of 1927 [§§ 17-1001 - 17-1011], or similar legislation.
