(Undated-AP) -- A Web site is selling the most secret document of top college and pro football programs.
The play books are available to anyone for just under $10 to around $40 -- depending on the number of pages in the book.
The site was created six weeks ago by three Texas high school coaches.
They say their goal is to provide resources to high school coaches around the country. Because the play books aren't copyrighted, they are considered public domain.
Co-founder Henry De Keratry wouldn't say how the play books are being obtained.
The site offers copies of 108 play books -- including the ones used by Oklahoma and Oklahoma State.
