The Ruffner family has a proud history in reference publishing. The library world widely recognizes Frederick Gale Ruffner Jr. as a pioneer in the industry. From humble beginnings in Detroit in 1956, Fred Ruffner and his wife, Mary, built Gale Research Company, working first at their kitchen table and then at a rented desk in the Book Tower.

In 1985, Fred Ruffner and his son Peter founded Omnigraphics. From the start, the Omnigraphics mission has been to provide authoritative and engaging reference resources to libraries and schools. Spanning the areas of biography, history, health, culture, and ready reference, our products have been consistently recognized for demonstrating the same uncompromising quality that is the hallmark of the Ruffner name.

The mission is unchanged today, even if the complexity of information and the many ways it can be consumed has changed. Omnigraphics is now part of Aggregate Intelligence, Inc, an innovative information intelligence company focused on providing high quality content and data to help people and companies make better decisions and live better lives. We are committed to high quality content, delivered in innovative and traditional ways that suit the user of that content.
