Classify

Classify was a FRBR-based prototype designed to support the assignment of classification numbers and subject headings for books, DVDs, CDs, and other types of materials.

This project applied principles of the FRBR model to aggregate bibliographic information above the manifestation level.

Bibliographic records were grouped using the OCLC FRBR Work-Set algorithm to form a work-level summary of the class numbers and subject headings assigned to a work.

The Classify database was accessible through a user interface and as a machine-to-machine service.

The database provided access to more than 46 million work summaries that contain

  • Dewey Decimal Classification (DDC) numbers, 
  • Library of Congress Classification (LCC) numbers, 
  • National Library of Medicine (NLM) Classification numbers.

Users were able to retrieve a summary by ISBN, ISSN, UPC, OCLC number, author/title, or subject heading.

Classify records also included subject headings from the Faceted Application of Subject Terminology (FAST) scheme.
