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

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 lib-raven@lists.cam.ac.uk

Cambridge University Library
