Ohio Rev. Code § 3329.07
The board of education of each city, exempted village, and local school district shall cause it to be ascertained and at a regular meeting determine which, and the number of each of the textbooks or electronic textbooks the schools under its charge require. The treasurer at once shall order the textbooks or electronic textbooks agreed upon from the publisher, who on the receipt of such order must ship the textbooks or electronic textbooks to the treasurer without delay. The treasurer forthwith shall examine the textbooks or electronic textbooks, and, if found right and in accordance with the order, remit the amount to the publisher. The board must pay for the textbooks or electronic textbooks so purchased and in addition all charges for the transportation of the textbooks or electronic textbooks out of the general fund of said district or out of such other funds as it may have available for such purchase of textbooks or electronic textbooks. If such board at any time can secure from the publishers textbooks or electronic textbooks at less than such maximum price, they shall do so, and without unnecessary delay may make effort to secure such lower price before adopting any particular textbooks or electronic textbooks.
