The “Google Myth”
If you can’t find it on Google,the information doesn’t exist.

Why Do Students Like Google and Google Scholar?

What Students Don’t know
Links for many articles on Google Scholar require subscriber login or an access fee.
Many libraries have already paid for subscriptions.
Other databases may be more relevant to the topic.
Google Scholar advanced search is not very powerful.
![Page 8: Taking the Library Back from Google Abe Lederman, President and CTO iGroup, October 18-20, 2007.](https://reader033.fdocuments.in/reader033/viewer/2022051216/56649ea85503460f94bab364/html5/thumbnails/8.jpg)
So Why NOT Google Scholar?
• “Scholarly content” intermixed with “non-scholarly” content
• Spotty coverage, requires publisher cooperation
• Poor relevance (citation counts don’t seem to help)
• Unable to limit searching to specific sources
• Difficult to find the needles in the haystack

Tennant’s Tenets
Roy Tennant: Internationally known speaker and writer on library and information technology issues.
• Only librarians like to search, everyone else likes to find.
• All things being equal, one place to search is better than two or more.
• Services should be placed as close to the user as possible.
![Page 14: Taking the Library Back from Google Abe Lederman, President and CTO iGroup, October 18-20, 2007.](https://reader033.fdocuments.in/reader033/viewer/2022051216/56649ea85503460f94bab364/html5/thumbnails/14.jpg)
Tennant’s Tenets (cont.)
“Good enough” is often just that. Our ability to create effective one-stop
searching is dependent on our ability to appropriately target user needs.
The size of the result set doesn’t matter as much as how the results are presented. (‘the Google Lesson’)
![Page 15: Taking the Library Back from Google Abe Lederman, President and CTO iGroup, October 18-20, 2007.](https://reader033.fdocuments.in/reader033/viewer/2022051216/56649ea85503460f94bab364/html5/thumbnails/15.jpg)
