Supplementary books and other instructional materials shall neither displace nor be used to the exclusion of basic textbooks.
The local board, at all times, has sole authority and discretion to determine whether a challenge has merit and whether challenged material should be retained or removed.
All textbook contracts made under this subsection shall include a clause granting to the local board of education the license to produce braille, large print, and audiocassette tape copies of the textbooks for use in the local school administrative unit.
