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."
