DESCRIPTIONThis is a slightly modified version of Think Like a Librarian for a different school district I'm working with.
- 1.Think like a librarian
Database tips & tricks
LeAnn Suchy, Metronet
2. Visible versus Invisible Web
Visible Web(often called Surface Web)
Stuff you find via search engines like Google, Yahoo, Bing, etc.
Invisible Web (often called Hidden Web or Deep Web)
Things not searchable by regular search engines
3. Visible Web
Last year Google indexed its trillionth webpage (1 trillion unique URLs)
Google has indexed about half of the Visible Web
Results are relevancy ranked
Over 200 factors determine relevancy
Popularity is a large factor
Hits a page gets is another factor
4. Invisible Web
Invisible Web is anywhere from 100 to 500 times bigger than the Visible Web (or even bigger?)
Search engines like Google cant index the Invisible Web because:
Items found via a query
5. Invisible Web is important
Search engine relevancy rankings for Visible Web sometimes arent all that relevant
Some tools to help navigate Visible Web to find better resources:
Librarians Internet Index: http://lii.org/
More for higher ed, but might be helpful
Invisible Web is way larger than Visible Web and has a lot more credible sources
6. How do I find Invisible Web?
Database through the government, libraries and state of MN
Databases through your school
Today were focusing on:ELM databases (ELM = Electronic Library for MN)
7. ELM - http://www.elm4you.org/

17. Before recommending, explore
Ask these questions of the database:
What type of content is provided?
How many publications are included? Years?
How frequently is it updated?
What navigational tools are provided?
Are there tutorials? A help section? Search tips?
How are search results displayed?
Can I save, email or print articles? RSS feeds?
Which students would best be served by this?
These questions and more are on Database Exploration Checklist
