Using Dewey Differently

Learn about the innovative DeweyBrowser and LiveSearch tools developed by OCLC Research Team, offering efficient searching and browsing capabilities by Dewey Decimal Classification (DDC) and employing FRBR algorithms to group related records. With human and machine-readable interfaces, these tools enrich records with DDC numbers and enable quick retrieval of relevant information. See demos of Elfquest, Frugal housewife, Say it in Polish, and Senate ethics manual.
