Just-in-case
Federated SearchingExamples: Systems developed at institutions
(e.g., Los Alamos National Laboratories; DTV, Denmark; Max Planck)
Scirus CrossRef Search Google Scholar
Google ScholarGoogle Scholar is different It’s Google; people love it. Has unparalleled software and
hardware resources Uses sophisticated crawling techniques Relies on well-established
collaboration with publishers Huge!
Google ScholarAdvantages: Quick Familiar Available System has full control over the data
Sophisticated searching Relevance ranking Matching …
Google ScholarDisadvantages: Secretive and vague about
Definition of scholarly information Scope, coverage, and accuracy of the content Relevance ranking algorithm Business model
Not trustworthy?Note: Still in beta-test
Google ScholarDisadvantages: Data is not complete Data is not up-to-date Citation information not reliable No way to scope searching No institutional branding No output tools No personalized services* No library control!
Google ScholarOpenURL linking Available since May 10, 2005 Enable library-defined services via a
link resolver However: require the upload of
holdings into Google Scholar
Metasearching
Metasearching
Metasearch SystemsAdvantages: Fully controlled by the library Provide access to known, reliable resources Up-to-date* Enable focusing on specific scope Can be tailored to specific users Customizable; enable local branding Integration with local system
Metasearch SystemsDisadvantages: Performance Configuration of resources* Processing of results applies to
retrieved records Require maintenance
Different types of users, different types of searches
Research needs differ from one user to another
Search versus locate Searching can be disconnected Four levels of research:
Google Google Scholar Metasearch systems Native interfaces
Is Google Scholar Here to Stay? Probably so, depending on Google’s
plans And it will certainly be used by end
users
If you cannot beat them, join them* Depends on the business model OpenURL linking was a good sign Encourage Google Scholar to make it
a better resource
Making Google Scholar Better
Meanwhile, educate! Include Google Scholar as well as
metasearch systems in introductory courses
Encourage instructors to refer to the resources for research
Use the library tools to provide a better research environment
Educate Our Users
Conclusions
Metasearch systems are much more “librarian-approved” than Google Scholar*
However, users will use Google Scholar no matter what
For the research environment, Google Scholar is better than Google
Good research experience and education are required
Thank you!
