    Abstract
    This article explores the history of the representation of the Dewey Decimal Classification (DDC) in the Machine Readable Cataloging (MARC) formats, with a special emphasis on the development of the MARC classification format. Until 2009, the format used to represent the DDC has been a proprietary one that predated the development of the MARC classification format. The need to replace the current editorial support system, the desire to deliver DDC data in a variety of formats to support different uses, and the increasingly global context of editorial work with translation partners around the world prompted the Dewey editorial team, along with OCLC research and development colleagues, to rethink the underlying representation of the DDC and choose the MARC 21 formats for classification and authority data. The discussion is framed with quotes from the writings of Nancy J. Williamson, whose analysis of the content of the Library of Congress Classification (LCC) schedules played a key role in shaping the original MARC classification format.

    Abstract
    Magda Heiner-Freiling argued for assignment of extra DDC numbers for improved access, including table numbers and other parts of numbers as well as fully built numbers, and for coding to identify component parts of built numbers. Changes to the MARC 21 Bibliographic format that support her approach are found in MARC Proposal No. 2008-01 Representation of the Dewey Decimal Classification (DDC) System in MARC 21 formats. The new 083 Additional Dewey Decimal Classification Number field is used for assignment of extra Dewey numbers for improved access. The new 085 Synthesized Classification Number Components field is used to identify component parts of built Dewey numbers. This paper uses specific examples to show how the new fields can help improve access.
