This is a no brainer for librarians (I hope), but a recent report comes up with the stats.
“But we, as library folk, should care. It means we should be using metasearch engines. Or we should be using more than one engine at a time. We should try to educate our users about this. We should try to make it clear that if you’re looking for research, for comprehensive answers, one engine ain’t gonna do it for ya.”
Great advice. Despite the fact the report was commissioned by a metasearch engine which has a lot to gain from the results going in the direction that they did, I applaud it.
Librarians who put in one or two keywords into Google are unnecessary middlemen. Anyone can do that. We need to go beyond that.
One last point: In the past many metasearch engines did not incorporate the entire databases of the engines they purported to search. If you are going to use these engines, make sure you are getting results as extensive as those that would appear in a search of the engine on its primary site.
