Okla. Stat. tit. 70, § 70-16-119: Sample textbooks

All advance or sample copies of textbooks or any edition thereof

furnished to any member of the State Textbook Committee, or to any

individual for the purpose of obtaining a selection of the textbook

by the State Textbook Committee, shall not be sold by the recipient

thereof, but shall be disposed of as may be prescribed by the rules

of the State Board of Education. Any advance or sample textbook or

any edition thereof furnished to a member of a local textbook

committee, or to any school official or individual for the purpose

of obtaining a local adoption of the textbook, may be returned to

the publisher for credit if the cost of such book was charged

against the value of textbooks allowed such school district.

Publishers shall pay the cost of shipment on returned samples. All

publishers having contracts to furnish textbooks to the State of

Oklahoma shall be required to file with the State Board of

Education, not later than the first day of January and the first day

of July of each year following the dates of their respective

contracts, a sworn statement showing the names and addresses of all

persons to whom they have furnished, during the preceding six (6)

months, any advance or sample copies of such textbooks, or any

edition thereof, together with the numbers and titles of such

textbooks furnished to each such recipient, and a failure to do so,

or to give accurate and complete information concerning the same,

shall authorize the State Board of Education to cancel the contract

of such publisher.
