    Abstract
    The database used to publish the 20th edition of the Dewey Decimal Classification (DDC) was produced on ESS (Editorial Support System). Systematic changes are being made in the database that will facilitate (1) converting ESS records to the USMARC format, (2) searching for component parts of and analyzing synthesized DDC numbers, and (3) tracking hierarchical relationships not expressed by the DDC notation.
