Here's an article to bookmark from the newsletter of the ABA General Practice, Solo & Small Firm Division: "Sites For Sore Eyes: Fun and Handy Reference Sites That Rock!" by Jim Calloway and Courtney Kennaday--
It’s not all about Google, people! There actually are websites that make your search easier and give you better results than the wild hits search engines often produce.
There are a number of references sites listed in the article, but the recommendation of Refdesk.com -- a site I didn't know about -- is one you definitely shouldn't miss. Thanks to Celia Elwell for the link.
