My friend David Warlick gave me a great tip about searching the Web. Instead of starting with a huge search engine such as Google, start small. Pick an engine with a smaller database, such as Yahoo, and work through its directory, which is arranged by subject and sub-topic. Then, having identified one or two high-quality Web sites, go back and create a search phrase based on frequently found terms in the pages you’ve found. Now proceed to a big search engine and plug in these keywords for your search. Focus is everything: Get the search terms right and you’ll wind up with a much more useful list of results.
