Visible versus Invisible Web<br />“Visible Web” (often called “Surface Web”)<br />Stuff you find via search engines like Google, Yahoo, Bing, etc.<br />“Invisible Web” (often called “Hidden Web” or “Deep Web”)<br />Things not searchable by regular search engines<br />Subscription databases<br />
Visible Web<br />Last year Google indexed its trillionth webpage (1 trillion unique URLs)<br />Google has indexed about half of the Visible Web<br />Results are relevancy ranked<br />Over 200 factors determine relevancy<br />Popularity is a large factor<br />Hits a page gets is another factor<br />
Invisible Web<br />Invisible Web is anywhere from 100 to 500 times bigger than the Visible Web (or even bigger?)<br />Search engines like Google can’t index the Invisible Web because:<br />Items found via a query<br />Passwords<br />
Invisible Web is important<br />Search engine relevancy rankings for Visible Web sometimes aren’t all that relevant<br />Some tools to help navigate Visible Web to find better resources:<br />Librarians Internet Index: http://lii.org/<br />Infomine: http://infomine.ucr.edu/<br />More for higher ed, but might be helpful<br />Invisible Web is way larger than Visible Web and has a lot more credible sources<br />
How do I find Invisible Web?<br />Think DATABASES<br />Database through the government, libraries and state of MN<br />Databases through your school<br />Today we’re focusing on: ELM databases (ELM = Electronic Library for MN)<br />
Many more<br />Over 50 ELM databases<br />More databases available through your school, so talk to your media specialist<br />And now, think like a librarian…<br />
Before recommending, explore<br />Ask these questions of the database:<br />What type of content is provided?<br />How many publications are included? Years?<br />How frequently is it updated?<br />What navigational tools are provided?<br />Are there tutorials? A help section? Search tips?<br />How are search results displayed?<br />Can I save, email or print articles? RSS feeds?<br />Which students would best be served by this? <br />These questions and more are on Database Exploration Checklist<br />
Between now and our meeting<br />Check out the information under Month 4 in the wiki, including the Database Exploration Checklist worksheet<br />Go into the ELM databases (or databases linked from your school library) and use the worksheet to analyze a couple databases<br />Blog about your experiences using the databases<br />When we meet in-person: Be ready to tell us about databases you think might be helpful for you and/or your students<br />
