Nationwide Learning Resources has been publishing free books for students for over twelve years.

Grade school students write and illustrate a book, then the company will publish the book for free.

Additional copies are made available for sale to family and friends.

Monday's historic four millionth book was authored by a sixth grader in Colorado.

The company surprised the author with copies of the book and a one hundred dollar scholarship during a school assembly.

Nationwide celebrated the occasion with an "Associate Appreciation Day".

CEO Joe Grigous says this business could not continue to be successful without the excellent staff.
