Search Engines and the Invisible Web Steven M. Cohen Rivkin Radler, LLP Growing Great Librarians NYLA/YSS Conference

What We Will Discuss Who Cares about this stuff? What’s New in the Search Engine Biz. Have you seen these? Why not just “Google” it? The Invisible Web

Who cares?

Why it Matters You help children and Young Adults find information. They trust your abilities. You owe to them your knowledge of search engines. You are their search engine. Librarian, know thyself.

What’s Happening in the Biz

What’s Happening in the Biz! Northernlight is finished. Alltheweb and Altavista have been bought by Overture. Meta search engines are making a comeback. The “I’m bigger than you are” fight is over. Engines are trying to better their algorithms.

What’s Happening (cont’d ) Everything is Google, Google, Google. Ask Jeeves is still going strong. Yahoo is still in the running. Advanced search sections are becoming more advanced. Subject specific engines are all the rave.

Have you seen these engines?

Teoma

GigaBlast

IxQuick

Feedster

Why Not Just Google?

Google only carries a small portion of the Web. Do you rely on only one reference book? Other engines might have indexed what Google missed. Google’s database may not be as fresh. What if…

Think I’m Wrong About Google? Pick a Random URL Place it in the Google search box with info: before the URL -If it comes up, it is indexed by Google -If not, then it is not indexed

Not indexed by Google, but...

The Invisible Web

Web information that does not get indexed by the major search engines. Hidden mostly in databases or have robot.txt file attached Data created on the fly from the backend (cgi-bin, etc) More than ¾ of information on the Web is part of the IW.

Examples of the IW Online telephone and address databases News engines Professional look-up services (AMA) Movie and Book Reviews Education databases (ERIC) Medical databases (Medline)
