About Us

Our Story

Topical Review Book Company was founded in 1936 in Auburn, New York by former teacher and principal Clarence L. Williams. His vision was simple: create review materials that actually help students succeed. 

For nearly a century, we have grown to be known as the “Little Green Book Company, a nod to the distinctive green covers of our review books. We have grown into a trusted name in New York State Regents Review, while remaining proudly family owned, now transitioning into our fourth generation.

Topical Review Book Company is currently based in the Irish Hills of Michigan. While we primarily serve New York State, we are happy to accommodate schools and educators wherever our materials are needed.
