The main obstacle for most people, I suggest, is this: brain death is usually sudden death a road accident, a stroke, violence and people arrive at the hospital tofindsomeone they love, who was in good health only a few hours earlier, now dead or dying.
So if you're trying tofind medical information for yourself or someone you love, and you're not lucky enough to have access to a professional research librarian, what do you do?
After all, if the web can help two isolated hearts findlove, or connect the owner of an unwanted garden gnome with someone keen to buy it, surely it can help an editor find the freelancer of his dreams and vice versa.
