Whenever people talk about the perils of using the Internet to do research I cringe. Generally, people who disdain using the Internet cite Wikipedia as a main problem. Of course, Wikipedia has some inaccurate information. But then, so does the Encyclopedia Britannica and any other source which is subject to typos, incomplete research, and human bias.

I teach courses at a community college. One of the problems I see with students using the Internet for their research is that they cannot discriminate amongst their sources. You and I, as attorneys, may be able to discern what might not be trustworthy or what may need further verification. My students, though, consistently lack that skill. The Internet is a marvelous tool. Yet, I think we need some sort of way to vet the junk from the jewels. My mind is too limited to figure out how that process might look.
