An investigation has found a widespread practice of people and businesses selling the books that Dolly Parton gives away for free.

Parton’s Imagination Library has become a staple for Tennessee families, providing free books each month to more than a million children ages birth to five years old.

On the website for Imagination Library, there is a disclaimer that the books are not to be resold, and in each book, there reads another warning that they are not for sale.

Books have been found on shelves in various Goodwill stores, used book stores and yard sales.
