OCLC BISAC Initiatives

• OCLC researchers and Dewey editors are collaborating on a project to create authority records for BISAC subject headings and add Dewey numbers to the records

• BISAC subject headings, including usage notes, are coded according to the MARC 21 format for authority data

• Dewey numbers from DDC 23, the latest edition of Dewey, are applied to the records by the Dewey team


Dewey Numbers: Mapping guidelines

• The topic represented by the subject heading either equals/approximates the whole of or is explicitly included in that number

• If the topic matches more than one Dewey number, multiple numbers may be added


Examples

• DDC: 1 083 04 152.47 $2 22 $5 OCoLC-D

150 __ SELF-HELP $x Anger Management

• DDC: 2 083 04 372.7 ‡2 22 ‡5 OCoLC-D

083 04 510.712 ‡2 22 ‡5 OCoLC-D

150 __ EDUCATION ‡x Teaching Methods & Materials ‡x Mathematics

• DDC: Many 150 __ BIOGRAPHY & AUTOBIOGRAPHY ‡x Rich & Famous

• Looking up literal and mapping: • COOKING—Beverages—Beer —> 641.623

• Deriving Dewey Summaries as broad subject description:

Kindred Works (Dewey-driven Discovery of Related Works) • What is it?

• Content-based recommender service • Leverages DDC, Classify & WorldCat API

• Consists of a demonstration interface & API • Accepts OCLC number or ISBN as input

• What do you get? • Returns a list of related resources (title, author, isbns) • Results can be limited to the holdings of a given institution

• Next Steps • Release as a prototype service • Collect usage data (e.g., rate the match) • Prototype a mobile app • Continue to refine the recommender logic
