CHICAGO March 27, 2008--R.R. Donnelley & Sons Company and EDGAR Online, Inc. announced today that they have collaborated to launch TryXBRL.com, the world's first public Web site that allows access to view and analyze complete XBRL-tagged financial statements for over 12,000 publicly-traded corporations.

XBRL, the eXtensible Business Reporting Language, is the global open standard for preparing, distributing and analyzing financial statement data and is expected to be mandated as the filing format of the Securities and Exchange Commission in the near-term.

Tom Juhase, President of RR Donnelley's Financial Services group said, "Open access to financial statements tagged in XBRL allows corporate finance teams to build practical knowledge about this important technology. As an early adopter and the leading XBRL filing provider for companies participating in the SEC Voluntary Program we provide a cost-effective, full service approach to XBRL translation."

TryXBRL.com benefits anyone interested in learning about XBRL as applied to real-world financial statements. Corporate finance professionals exploring filing in XBRL with the SEC can educate themselves about the XBRL tagging process and view their own historical financial information in XBRL format. Investors and analysts can experience firsthand how XBRL reduces the complexity and costs associated with analyzing performance data.

"Our goal has been to deliver solutions that do not require technical expertise or excessive time commitments by corporations wishing to take part in the SEC Voluntary Program or to familiarize themselves with XBRL," said Philip Moyer, President and CEO of EDGAR Online, Inc. "EDGAR Online has already created the world's only repository of XBRL formatted data for all 12,000 U.S. filing companies. We are providing open access to our vast XBRL database through a solution that enables corporations to begin filing XBRL content with the SEC in as little as a few hours."

RR Donnelley and EDGAR Online have collaborated to deliver XBRL filing solutions to corporations since 2005.
