Shearer Mod Shearer Mod Presentation Transcript

  • Google Scholar, OpenURL and the Academic Library Tim Shearer UNC Libraries
  • Why worry about Google?
    • Crawled copy(ies) are often commercial.
    • On-campus, may have institutional access to commercial content…or not.
    • “ Appropriate” copy.
    • We want to insert licensed content into the click stream on- and off-campus.
  • How to do it?
    • Most obviously, you must first have an institutional resolver.
    • We do: Serials Solutions.
  • Brief tour of OpenURL within Google Scholar
    • Google Scholar pilot - “Scholar Preferences.”
    • Client side tools.
    • Server side arrangements (extending the Google pilot project).
  • Client based (browser specific)
    • Firefox extension (Peter Binkley, U Alberta)
    • Users:
      • Must have appropriate version of Firefox.
      • Must know that “appropriate copy” is an issue.
      • Must know that UNC has an extension.
      • Must actively install it.
  • Client based (vendor neutral)
    • Bookmarklet (Peter Binkley, U Alberta)
    • Users:
      • Must know that “appropriate copy” is an issue.
      • Must know that UNC has a bookmarklet.
      • Must actively install it.
      • Must activate it on every Google Scholar results page.
  • Pros of client based
    • Google not involved in any way… “stealth content.”
    • Entirely controlled by institution and user
      • No holdings information shared with Google
      • Can use your standard OpenURL, institution-branded icon for linking.
  • Server based
    • Server knows about institution:
      • Resolver
      • Link text
      • IP address range
      • (and holdings?)
    • -additionally-
    • Server may know about end user:
      • Client cookie indicates user-selected institution(s).
  • Serials Solutions
    • Serials Solutions and Google Scholar arrangement.
    • As customer, UNC Chapel Hill may opt to participate, and does so.
    • On-campus users have OpenURL links.
    • Off-campus users may set preferences (cookie) to make links available.
  • Cons of server based (in a Google world)
    • Google will not support images for resolver linking.
        • No UNC icon branding.
        • Users no longer have consistent visual cues.
    • Google requires electronic holdings.
    • But… it works.
  • What more can we do for users?
    • Often the most convenient copy (main Google link) is something already licensed for an academic user.
    • Ideal for on-campus users.
    • What about off-campus users?
    • University of Texas at Austin is proxying Google Scholar!
  • Can UNC proxy Google Scholar?
    • License EZ Proxy.
    • Yes, it works.
    • Form interface, use middleware so that users may type query into UNC page (authenticate if off-campus) and proceed seamlessly to Google Scholar results.
  • We can do it. What should we do with it?
    • Add to E-Resource finder?
    • Make a Google Scholar page?
    • Add to our home page?
  • The Discussion
    • How useful is Google Scholar?*
      • Coverage/scope
      • Timeliness
      • Recall and precision
      • Relevance
      • Accuracy
      • Output
      • (*apologies to Roy Tennant, CDL)
  • The Discussion, continued…
    • Given the limitations of Google Scholar, why give it the Library’s imprimatur at all?
    • Given its limitations, why give it preferred status as the only electronic resource on our home page?
  • The discussion, continued…
    • Well, it is useful.
    • Faculty are enthusiastic.
    • Students are enthusiastic.
    • They are using Google Scholar.
    • Embrace the inevitable?
    • Get licensed content into the click stream regardless of location.
  • Strange but true
    • Books appear in Google Scholar
    • Students have asked the instructional staff, “Do we have this?”
  • What happened?
    • Strong administrative support for adding to the Library’s home page.
    • Went live April 18 th 2005, in time for the end of the Spring term.
    • Library instruction has begun to explicitly include Google Scholar in some classes (Fall 2005).
