One of the best benefits of being a registered law student is unrestricted access to both Lexis and WestLaw. Students often have no idea how much these services cost until they experience a rather rude awakening during their first post-graduation law job (for example, ONE search in the "All Fed Cases" database of either service costs around $120). Suddenly, the cost of these services becomes important. Sue Altmeyer, a law librarian at Cleveland State University School of Law has written an excellent introduction on how to search "frugally" using these services.
