The trustees of the library shall not, without permission from the commission, hereafter incur any indebtedness or liability on account of the library in excess of the amount of money available for the payment of such indebtedness or liability, but shall so manage the affairs of the library so that the annual revenues shall be ample to pay all expenses and obligations of the library. Any loan of city funds to satisfy an indebtedness incurred by the library in excess of its budgeted authority shall accrue interest at ten percent (10%) per year. (Ord. 1715A, 12-3-2007)
