The OpenURL
What are OpenURLs?How do they work exactly?What is SFX?What’s so “special” about SFX, and how
easy is it to maintain?

History of the OpenURL & SFX
Initial concept developed at the University of Ghent by Herbert Van de Sompel (now at the British Library)
His product, now known as SFX, was acquired by ExLibris in 2000, and has been sold to nearly 200 customers in some 20 countries

Responding to user needs
Users want seamless access to e-journalsStudents feel frustrated with too many
steps trying to use library resourcesWith vast amounts of information now
available, expectations are high: students want it any time, anywhere
Speed is the key today: fast computers, fast connections, and fast delivery of resources

Static URLs
Static URLs are location dependent: link refers to a single copy of a resource at one location
Static URLs cannot take into consideration the user’s affiliation with the library
Static URLs must be verified periodically

The OpenURL
The nature of the OpenURL is tied directly to the article and not a specific location
Resolution service (SFX) resolves the OpenURL to a copy or a set of services appropriate for that user: SFX can also retrieve multiple versions of a full-text article regardless of where it is located

The OpenURL
Provides context-sensitive linkingCombines full-text and extended services
with user authentificationThe OpenURL contains elements that
identify the user and information about the desired article

SFX Considerations
Publishers and aggregators must use OpenURLs rather than traditional URLs in order for SFX to work
Librarians determine what services the library will offer: what options a search in a database will provide
In addition to full-text, librarians define what extended services will be offered, including links to the OPAC, abstracts, ILL services, and search engines

More SFX Considerations
Be aware that each vender presents SFX differently; this can be challenging to the user
Not all products can be linked to SFX; users must be made aware which products are SFX-enabled
