There's something other than Google?

Joyce Valenza is a big proponent of Richard Byrne's "Beyond Google: Improve Your Search Results." I am emailed this article to myself and will use it very soon. I know Google can provide useful results but it is certainly not the only option. I get highly annoyed when educators say "don't use Google at all." Google has a lot to offer. So do other sites. I need to do a better job "selling" databases, etc. and teaching HOW to search effectively.
