The ability of virtually anyone to post anything to the web means that the web contains information on just about any topic, and unfortunately, much of this information is unreliable, inappropriate, or simply uninteresting. In addition to educational resources, scientific data, and job postings, there are also personal vanity homepages, advertisements, and the exhortations of those who just want to be heard, as well as pornography and guides to criminal activity. This mass of information is problematic to the student researcher who is attempting to find useful, reliable information.
