PHILADELPHIA, Sept. 16 /PRNewswire-FirstCall/ -- CDI Corp. (NYSE: CDI) today announced that it has been named to the InformationWeek 500, an annual listing of the nation's most innovative users of business technology, for the ninth year in a row. The 2009 InformationWeek 500 companies were revealed on September 14, 2009 at an awards ceremony held during the InformationWeek 500 Conference in Dana Point, California.

For the past 21 years, InformationWeek has identified and honored the nation's most innovative users of information technology with its annual listing. The list is unique among corporate rankings because it spotlights the power of innovation in information technology, rather than simply identifying the biggest IT spenders.

"For over 20 years, the InformationWeek 500 has honored the most innovative users of business technology," said InformationWeek Editor-in-Chief Rob Preston. "Year after year, InformationWeek 500 companies harness technology to improve efficiency, boost productivity, drive revenue, and establish a competitive advantage. We applaud this year's winners, and the CIOs and other executives whose ingenuity and risk taking are at the center of business technology innovation."

"We are constantly evaluating our business technology strategies and projects to maximize efficiencies," said Vince Squillacioti, Senior Vice President, Chief Information Officer of CDI. "It is our goal to develop leading-edge, cost-effective solutions that provide a superior return on invested capital."
