  2. DeweyBrowser • The DeweyBrowser is a research prototype that supports searching and browsing collections of resources organized by Dewey • The prototype was developed to make the most of DDC numbers assigned to library materials and to explore the use of AJAX (Asynchronous JavaScript and XML)

  3. DeweyBrowser • The interface presents search results at three levels, i.e., the three main summaries of Dewey • To use the prototype, a user navigates up and down the Dewey hierarchy by clicking on a category or enters a search term • The categories are color-coded to indicate where matching records occur • red, orange, and yellow (warm colors) — many records • green and blue (cool colors) — fewer records • white — no matching records

  4. DeweyBrowser • Summaries can be displayed in English, French, German, Spanish, or Swedish • Search and browse results can also be limited to resources written in a particular language

  5. DeweyBrowser • The DeweyBrowser has been deployed over three collections of resources: • ebooks - 210,000+ electronic books • wcat – 2.2 million of the most widely held WorldCat records • abr14 – selected data from the Abridged Edition 14 of DDC • WorldCat and ebooks collections are linked to the Find in a Library Web service

  6. Dewey Browser • The Abridged 14 collection includes a collaborative editing feature that enables authorized users to suggest index terms for a DDC class (Suggested terms) • Suggested terms will be delivered to interested users via RSS

  7. DeweyBrowser & AJAX • AJAX is an approach to programming web interfaces that allows user interaction with a web page without refreshing the whole screen • Using AJAX speeds up the interface by only requesting parts of a page • Refreshing only the part of the screen that changes tends to encourage exploration, behavior that is central to how the DeweyBrowser was designed to be used • The DeweyBrowser is an example of an entire application built using AJAX

  8. Curiouser • Curiouser is an approach to making the best use of data about items in WorldCat and a user interface for exploring and selecting works and items • The prototype interface • employs the OCLC FRBR work-set algorithm • exploits structured data in bibliographic, authority, and holdings records, • integrates techniques from FictionFinder for display and navigation of records in a FRBR context, • explores Web services and other data sources to enhance the utility of Open WorldCat

  9. OCLC FRBR Work-Set Algorithm • A work set is a group of bibliographic records with the same Author/Title key • A key is generated for each bibliographic record • Variant forms of names and titles are converted to established forms based on the OCLC authority file • Keys are sorted and compared to form work sets

  10. Family of Works* Original Russian Translation Pop-up book Annotated edition *See: Tillett, Barbara. 2004. What is FRBR?: A Conceptual Model for the Bibliographic Universe. Available at: http://www.loc.gov/cds/downloads/FRBR.PDF

  11. Examples • The lion, the witch and the wardrobe • Don Quixote • Joy of cooking • The bell jar
