"Dewey Decimal Classification numbers organize resources using a hierarchical structure that is ideal for browsing by subject area. To enhance the usefulness of DDC as an online tool, OCLC conducts research in these areas: developing customizable views of the DDC, enhancing links to other thesauri, improving links to other editions, transforming the captions into end-user language, and decomposing numbers and using the parts for improved access. This paper discusses these research areas."@en . . "Dewey 2000 cataloging productivity tools"@en . . . . . . . . . . .
