Overview
1. Background
2. eresources@cambridge - demonstration
3. Federated search issues
4. OpenURL Linking from Google Scholar & CSA
5. Authentication update
6. Questions ?
Cambridge University Library
I) Background – problems with eresource access
Cambridge University Library
Growing collections
• 20,000 + ejournals• 1,000 + ebooks• 300 + databases (each with thousands of
records) • All held on various different websites
Cambridge University Library
Cambridge University Library
Lots to search
• Searching everything – time consuming• Learning to use multiple interfaces - difficult• Authentication problems – still complex• ‘Just Google it’ ?
Cambridge University Library
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
Cambridge University Library
Two problems
• Lots of resources to search
• Ensuring links in databases point to journal holdings that we subscribe to
Cambridge University Library
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
Cambridge University Library
• eresources@cambridge
Cambridge University Library
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

Portal demonstration
• http://www.lib.cam.ac.uk/electronicresources/
Cambridge University Library
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
Cambridge University Library
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
Cambridge University Library
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
Cambridge University Library
2) OpenURL Linking
Cambridge University Library
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
Cambridge University Library
SFX
• We use SFX from Ex Libris • Market leader – used in 1,500 libraries
worldwide

What happens ?
Cambridge University Library
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’
Cambridge University Library
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

5) Authentication update
Cambridge University Library
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.
Cambridge University Library
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 [email protected]
Cambridge University Library
OffCampus authentication• Athens• Alternative Login or Institutional login
– UK Access Management Federation– University of Cambridge– Raven login
