  2. Overview • Background • eresources@cambridge - demonstration • Federated search issues • OpenURL Linking from Google Scholar & CSA • Authentication update • Questions ?

  3. I) Background – problems with eresource access

  4. Growing collections • 20,000 + ejournals • 1,000 + ebooks • 300 + databases (each with thousands of records) • All held on various different websites

  5. Lots to search • Searching everything – time consuming • Learning to use multiple interfaces - difficult • Authentication problems – still complex • ‘Just Google it’ ?

  6. Disconnection between citation and full text • Users may just find the citation they need on Web of Science … • But the link on Web of Science takes them to a ‘click here to purchase’ page instead the full text • Title held on another provider’s site

  7. Two problems • Lots of resources to search • Ensuring links in databases point to journal holdings that we subscribe to

  8. Two solutions (hopefully) • Lots of resources to search Federated Searching: CrossSearch • Ensuring links in databases point to journal holdings that we subscribe to OpenURL Linking: ejournals@cambridge

  9. eresources@cambridge

  10. eresources@cambridge • Simple ‘portal’ to eresources via the UL website • Alphabetical and subject lists of titles • Links to CrossSearch and ejournals@cambridge A-Z at subject level – steer people away from big searches • Integrated help

  11. Portal demonstration • http://www.lib.cam.ac.uk/electronicresources/

  12. Federated searching • Passes your search term to multiple resources at once • Returns and amalgamates results sets • Rely on access to and availiabity of third party sites

  13. Federated Search - good for… • Simple searching across a few multiple resources • Indentifying which resources best cover your subject area • Introducing users to the ‘native interface’ • Drilling down through large results set with clustering

  14. Issues with Federated Search • Lost in translation – one system’s idea of an author index may not match another • Lowest common denominator – the slowest resource will slow the whole search down • Myth of complete access – takes a long time to search it all

  15. 2) OpenURL Linking

  16. Open URL Linking • Puts links in citation databases that point to our link resolver • Our link resolver then passes the user to our specific full text holdings • Requires the maintenance of a Link Resolver ‘knowledge base’ • Used to populate the ejournals@cambridge A-Z

  17. SFX • We use SFX from Ex Libris • Market leader – used in 1,500 libraries worldwide

  18. ejournals@cambridge demo • http://www.scholar.google.com • http://csaweb102v.csa.com/ids70/quick_search.php?SID=j8kkd608rohaqmklbbjqv151u0

  19. What happens ?

  20. Good points • Increases value of A&I only resources - CSA, Google Scholar • Good for enriching personal lists of citations • Means that if we change a journal supplier, the link does not become ‘out of date’

  21. Not so good… • Only as good as the knowledge base • Rely upon supplier to keep their knowledge base up to date with developments in ejournal vendor supply • Databases must also support the OpenURL format in order to embed links to our resolver • Current problems getting links into Pubmed

  22. Questions … • emc59@cam.ac.uk

  23. 5) Authentication update

  24. On and Off-campus access • Only current staff and students of the university have access to electronic journals and online databases off campus • Requires a Raven password • In the library and elsewhere on campus most electronic resources (ejournals, online databases, ebooks etc.) are available to everyone so long as they are used on a non-commercial basis. Raven passwords are not normally required for this.

  25. Athens Raven • Athens passwords are being phased out by the UK academic community • No Athens passwords have been issued in Cambridge since 1 September 2007 • From 1 August this year Athens passwords still held by staff and students will cease to work • Raven passwords can be used wherever users are prompted for Athens passwords • Anyone having problems with Raven passwords or queries about them should be asked to e-mail lib-raven@lists.cam.ac.uk

  26. OffCampus authentication • Athens • Alternative Login or Institutional login • UK Access Management Federation • University of Cambridge • Raven login • First time you access a particular resource on a PC. • This sets a cookie so that the site sill take you directly to the Raven login page.

  27. Ejournal enquiries – email ejournals@lib.cam.ac.uk • Raven passwords – email lib-raven@lib.cam.ac.uk

  28. Questions … • Ed Chamberlain – Systems Librarian • emc59@cam.ac.uk
