Why Yahoo, not Google, should drive your search, by Steve Johnson, Chicago Tribune Internet critic, October 12, 2007: "The Yahoo [search] effort...is so impressive I'm going to make it my default searcher. Best is "Search Assist," an expandable box right below where you type your query that offers a bevy of clickable terms to help you refine it. A good reference librarian will write a specific, targeted search. Yahoo's search assist gets you close to librarian status, without the bother of getting an MLS degree."
