Google Scholar and Link Resolvers • Agenda • Google Scholar • OpenURLs • Link Resolver (SFX)
1. http://scholar.google.com • Preferences and defaults • Libraries to search • ip address range • Buttons • Full text • Physical copy • How does GS know about our holdings? • We tell them • WorldCat • Web crawling
2. OpenURLs • What are they? • “…a protocol for interoperability between an information resource and a service component, referred to as a link server, which offers localized services.” (from www.exlibrisgroup.com/sfx_openurl.htm) • “…The underlying concept of the OpenURL standard is that links should lead a user to appropriate resources” (from www.exlibrisgroup.com/sfx_openurl.htm)
OpenURLs cont. • Example: • http://owens.mit.edu:8888/sfx_local?sid=google&aulast=Oldenburg&auinit=SJ&atitle=Nanoengineering+of+optical+resonances&title=Chemical+physics+letters&volume=288&issue=2&date=1998&spage=243&issn=0009-2614
OpenURLs cont. • National Information Standards Organization • NISO Committee AX formed in 2001 • OpenURL version 0.1 specification http://www.exlibrisgroup.com/sfx_openurl.htm • OpenURL version 1.0 specification http://library.caltech.edu/openurl/Standard.htm
3. Link Resolver - SFX • Menu or Direct Linking? • Menu advantages: display alternatives provide more information • Menu disadvantages: slows the user down more mouse clicks
SFX cont. • Direct Linking Advantages: • rapid, seamless progression to the target article • (near) instant gratification Disadvantages: • Doesn’t exploit multiple FullText targets • Bypasses other library services
