A Board of Library Trustees may, by resolution, abolish a working cash fund established pursuant to Section 4-13 and direct the transfer of any balance in such fund, including any interest that has accrued, to the general library fund at the close of the fiscal year. However, if the board abolished a working cash fund under this provision, it shall not establish another working cash fund, unless establishment of the fund is approved by a majority of the voters of the city, village, incorporated town or township voting on the question at a referendum.
