    1. 1. Google Scholar, OpenURL and the Academic Library Tim Shearer UNC Libraries
    2. 2. Why worry about Google? <ul><li>Crawled copy(ies) are often commercial. </li></ul><ul><li>On-campus, may have institutional access to commercial content…or not. </li></ul><ul><li>“ Appropriate” copy. </li></ul><ul><li>We want to insert licensed content into the click stream on- and off-campus. </li></ul>
    3. 3. How to do it? <ul><li>Most obviously, you must first have an institutional resolver. </li></ul><ul><li>We do: Serials Solutions. </li></ul>
    4. 4. Brief tour of OpenURL within Google Scholar <ul><li>Google Scholar pilot - “Scholar Preferences.” </li></ul><ul><li>Client side tools. </li></ul><ul><li>Server side arrangements (extending the Google pilot project). </li></ul>
    5. 5. Client based (browser specific) <ul><li>Firefox extension (Peter Binkley, U Alberta) </li></ul><ul><li>Users: </li></ul><ul><ul><li>Must have appropriate version of Firefox. </li></ul></ul><ul><ul><li>Must know that “appropriate copy” is an issue. </li></ul></ul><ul><ul><li>Must know that UNC has an extension. </li></ul></ul><ul><ul><li>Must actively install it. </li></ul></ul>
    6. 6. Client based (vendor neutral) <ul><li>Bookmarklet (Peter Binkley, U Alberta) </li></ul><ul><li>Users: </li></ul><ul><ul><li>Must know that “appropriate copy” is an issue. </li></ul></ul><ul><ul><li>Must know that UNC has a bookmarklet. </li></ul></ul><ul><ul><li>Must actively install it. </li></ul></ul><ul><ul><li>Must activate it on every Google Scholar results page. </li></ul></ul>
    7. 7. Pros of client based <ul><li>Google not involved in any way… “stealth content.” </li></ul><ul><li>Entirely controlled by institution and user </li></ul><ul><ul><li>No holdings information shared with Google </li></ul></ul><ul><ul><li>Can use your standard OpenURL, institution-branded icon for linking. </li></ul></ul>
    8. 8. Server based <ul><li>Server knows about institution: </li></ul><ul><ul><li>Resolver </li></ul></ul><ul><ul><li>Link text </li></ul></ul><ul><ul><li>IP address range </li></ul></ul><ul><ul><li>(and holdings?) </li></ul></ul><ul><li>-additionally- </li></ul><ul><li>Server may know about end user: </li></ul><ul><ul><li>Client cookie indicates user-selected institution(s). </li></ul></ul>
    9. 9. Serials Solutions <ul><li>Serials Solutions and Google Scholar arrangement. </li></ul><ul><li>As customer, UNC Chapel Hill may opt to participate, and does so. </li></ul><ul><li>On-campus users have OpenURL links. </li></ul><ul><li>Off-campus users may set preferences (cookie) to make links available. </li></ul>
    10. 10. Cons of server based (in a Google world) <ul><li>Google will not support images for resolver linking. </li></ul><ul><ul><ul><li>No UNC icon branding. </li></ul></ul></ul><ul><ul><ul><li>Users no longer have consistent visual cues. </li></ul></ul></ul><ul><li>Google requires electronic holdings. </li></ul><ul><li>But… it works. </li></ul>
    11. 11. What more can we do for users? <ul><li>Often the most convenient copy (main Google link) is something already licensed for an academic user. </li></ul><ul><li>Ideal for on-campus users. </li></ul><ul><li>What about off-campus users? </li></ul><ul><li>University of Texas at Austin is proxying Google Scholar! </li></ul>
    12. 12. Can UNC proxy Google Scholar? <ul><li>License EZ Proxy. </li></ul><ul><li>Yes, it works. </li></ul><ul><li>Form interface, use middleware so that users may type query into UNC page (authenticate if off-campus) and proceed seamlessly to Google Scholar results. </li></ul>
    13. 13. We can do it. What should we do with it? <ul><li>Add to E-Resource finder? </li></ul><ul><li>Make a Google Scholar page? </li></ul><ul><li>Add to our home page? </li></ul>

    15. 15. The Discussion, continued… <ul><li>Given the limitations of Google Scholar, why give it the Library’s imprimatur at all? </li></ul><ul><li>Given its limitations, why give it preferred status as the only electronic resource on our home page? </li></ul>
