Law students who are interested in exploring the latest in online legal research tools may want to check out Ravel Law. Unlike Lexis and Westlaw, Ravel gives you a visual display of a case law search result so that you can see connections between cases. We've been experimenting with a few searches, and so far we've been favorably impressed with Ravel Law's search algorithm. For details about how Ravel Law works, you can review the short video tutorials on this page. Current USF law students have free access to the Advanced version of Ravel Law (includes unlimited case law searching, search history, and ability to star and annotate cases), but you must sign up with an @usfca.edu address.
Some drawbacks of Ravel -- it does not have ALL case law yet (they're working on it), so if you're researching an area where old case law is important (property; torts), you will want to stick with Lexis, Westlaw, or Bloomberg Law. Ravel is used exclusively for case law research -- statutes, regulations, and secondary sources are not yet available on Ravel.
