Washington Researchers is company that provides training and publications on competitive intelligence.  I have used their publications on several occasions and found them to be helpful and concise resources for researcher. 

The Washington Researchers website includes “The Ten Commandments of Internet Searching according to Washington Researchers.”   The commandments include some useful reminders that should streamline lawyers’ searching efforts. For example, know your search engine and use multiple searcher engines.   When you find relevant information in your search, “[c]onsider the source of what you find. Just because it is in print, doesn't mean it's true.” 

Perhaps the most important commandment is to watch the clock:  “If you don't watch yourself, you will spend hours looking for something that can't be found or you will end up surfing instead of searching.”
