  • What’s next in WorldCatMoving from providing access to data to selling servicesLinked data – starting to offer some datasetsFirst step is sharing, next step could be online delivery and circulation?
  • Initial Interface
  • Advanced Search Interface
  • Users are able to refine and customize searches

  • StrengthsResponds to user needs for simplified searching Encourages them to use it More emphasis on research in wider world of electronic information Link from Google Books to WorldCat to holdings of individual libraries Good advanced search function (limit by type of material, language, publication date, etc.)
  • Strengths (contd) Facilitates ILL by making collections of other libraries accessible Beneficial for collection analysis  Download list of titles to Excel  Facilitates creation of collection development policies High standards for cataloguing Extensive search results  But might also be considered weakness if people do not check relevancy?
  • Weaknesses Some librarians consider such systems to be obstacle for acquiring information literacy skills  Relevancy of searches, ease of searching Serials often not included High standards for cataloguing but perhaps more flexibility needed  Encompass records from many sources  Allow for creation of more records Make better use of automation for updates
  • Suggestion Tiered approach for standards (Turner, 2009, 275)  Basic rules for all records with more detailed rules being “best practices”
