DOUG!

Who (or what) is D.O.U.G.?  It's a handy way to remember: Don't Only Use Google!  Google is the most well-known search engine and is really useful, but - remember - one search engine doesn't find EVERYTHING (or even the best things) that is available online.  The best researchers use a variety of tools to find exactly what they are looking for.  Here are a couple of other tools to use for research:

IPL2 (Internet Public Library - Kids Section): You can use the search tool or browse through the subjects and interesting links from the homepage.

ZUULA :  This searches several of the top search engines at the same time, including Google, Bing, Yahoo, etc. There are many ways to personalize it.  Try it and let me know what you think!

EThemes:  This was developed by the University of Missouri and only includes results that have been reviewed.   The results are very accurate and kid-friendly.

Infoplease:  This is based on an almanac, but really includes a lot of information from many sources, including an encyclopedia.

And always remember:  no matter how you search, always use the 3-A Way to evaluate results!  Check out the Author, Accuracy, and Appearance before you use information from the site.
