Item 7.01    Regulation FD Disclosure

During the first quarter of 2005, the management of R.R. Donnelley & Sons Company (the “Company”) changed the Company’s reportable segments to reflect the new structure of the organization and the manner in which the chief operating decision maker regularly assesses information for decision-making purposes, including the allocation of resources. As a result, the Company’s book, European and Asian operations have been reported in the Publishing and Retail Services segment (previously reported in the Integrated Print Communications segment). The Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2005 describes the Company’s new segment structure.

The Company recently re-issued its historical financial statements for the three years ended December 31, 2004 and management’s discussion and analysis of financial condition and results of operations for the years ended December 31, 2003 and 2004 to reclassify prior periods to conform to this current reporting structure. The Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on May 18, 2005 contains the re-issued financial statements and management’s discussion and analysis of financial condition and results of operations.

The Company is furnishing herewith a schedule setting forth with respect to each of its revised segments certain operating income and margin information for each of the four quarters in 2004 and for the twelve months ended December 31, 2004. This schedule shows such information on the basis of generally accepted accounting principles (GAAP) and as adjusted for restructuring, impairment and integration charges. The Company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP measures, are useful because that information is an appropriate measure for evaluating the Company’s operating performance. Internally, the Company uses this non-GAAP information as an indicator of business performance, and evaluates management’s effectiveness with specific reference to this indicator. These measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

The information shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the Exchange Act), or otherwise incorporated by reference into any filing pursuant to the Securities Act of 1933, as amended, or the Exchange Act except as otherwise expressly stated in such a filing.
