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!
