Oregon Revised Statutes Education and Culture § 337.075

(1) The State Board of Education may adopt or reject any textbook contained in any proposal. If the terms and conditions for furnishing a textbook in all proposals relating to that textbook are considered by the board to be unreasonable or the textbook is considered to be unsuitable pursuant to guidelines and criteria established by the board, the board may reject the textbook.

(2) At the same or subsequent sessions, the board may receive new proposals for a textbook previously rejected and adopt the textbook in the same manner as other textbooks are required to be adopted. No proposal shall be considered unless the publisher has delivered without charge two copies of each textbook contained in the proposal to the Department of Education at least 60 days before the meeting.
