I have written about Google Scholar before. It is a great case finder, and is free. It contains the full text of just about every case ever decided, has a really good search engine, and has official pagination, internal linking to the full text of every cited case, a built in Shepard's like citator, which, with one click, will pull up every case that has cited the case you are viewing. $69 addon, CiteStack, creates pin cites, and memoranda on the fly, while you are doing Scholar research. Take three minutes and watch how CiteStack works in Google Chrome. Google Chrome, Google Scholar and CiteStack. A complete legal research solution.
