New paradigm for search 2

New paradigm for search “The Web, they say, is leaving the era of search and entering one of discovery. What's the difference? Search is what you do when you're looking for something. Discovery is when something wonderful that you didn't know existed, or didn't know how to ask for, finds you.“ Jeffrey M. O’Brien, "The race to create a 'smart' Google", http://money.cnn.com/magazines/fortune/ fortune_archive/2006/11/27/8394347/ 2

The OpenURL framework • 2001: first link resolver deployed commercially – SFX from Ex Libris • 2009: wide participation from the scholarly world: • Estimated 3000+ link resolvers around the world (~1700 SFX sites alone) • All major information providers (A&I, online journal providers, Google and more) participate as a source of OpenURL links and/or as a target for linking • Link resolvers are a key hub of activity across a distributed set of resources 7
