CHICAGO, May 7, 2001 - R.R. Donnelley & Sons Company's [NYSE: DNY] Crawfordsville, Ind., manufacturing plant has achieved a major customer quality assurance milestone in the printing and binding of books. With more than two million square feet of manufacturing space and 1,800 employees, the business was recommended for International Organization of Standardization (ISO) 9002 certification on March 1, 2001. The ISO recognizes businesses that have a quality control system in place that is executed effectively to ensure its products meet the quality expectations of its customers. "R.R. Donnelley has gone one step further to maintain a standard of quality for its clientele," said Indiana Governor Frank O'Bannon, acknowledging the importance of meeting these global standards. This is an enormous achievement in light of the complexity within R.R. Donnelley's Crawfordsville division. The first section of the north plant facility was completed around 1925, a few years after R.R. Donnelley joined the telephone directory printing business by building its first plan outside Chicago in Indiana. The plant moved into the core book printing business and produces approximately 200 million hard cover, soft cover and saddle wire books each year. "I applaud the achievement of the employees at your Crawfordsville facility," Indiana Secretary of State Sue Anne Gilroy stated in a letter congratulating the plant on the certification.
