# Classify Classify is a prototype service designed to support the assignment of classification numbers for books, DVDs, CDs, and many other types of materials. ## Overview The prototype provides access to more than 36 million WorldCat records that contain Dewey Decimal Classification (DDC) numbers, Library of Congress Classification (LCC) numbers, or National Library of Medicine (NLM) Classification numbers. The records are grouped using the OCLC FRBR Work-Set algorithm resulting in a work-level summary of the class numbers assigned a title. You can retrieve a classification summary by ISBN, ISSN, UPC, OCLC number, or author/title. Some examples are: ### Examples: The omnivore's dilemma (ISBN — 1594200823) Persepolis (OCLC# — 050670595) Akahige (UPC — 03742916882) O brother, where art thou? (UPC — 008817006925) La joven de la perla (Title in Spanish) On writing / King (Title & Author) ## Get Started Visit the prototype to view classification information for a title including a chart showing the top classes. ## Project Team Diane Vizine-Goetz (lead) Harry Wagner JD Shipengrover
