Sometimes journalists and others with difficult research assignments find it is practically necessary to learn the "answers'' before asking the "questions.'' This is not to develop pre-conceived (and likely misleading) notions about a topic that could narrow an inquiry; rather it is to become informed enough to ferret out what's really going on behind the scenes. By chance, on a referral from my wife who is involved in information brokering, I discovered Helen Burwell's "Online Competitive Intelligence'' and found it to be a worthwhile and wide-ranging resource for my work in journalism. Of course, the first thing many of us will turn to is the array of sites and references to see if there are any nuggets we've missed in our on-line research. Burwell's book likely will provide some of these -- (one reference I'd never thought to seek is overseas Yahoo). But the most valuable resource is the organization of the book's topics, which provides a terrific, systematic checklist for research, in particular for unfamiliar areas. Overall, a most worthy reference guide.
