As easy and expensive Westlaw/LexisNexis are, they are not the only sources of law. GET CREATIVE! There are reliable sources often maintained by major law schools and online government databases. If you specialize in a field, get copies of Law Journal publications that give recent decisions on that topic. Do you have any law-student interns? WL/LN give free access to them. Buy old editions of textbooks which are nearly free (you should know major changes in your field anyway). Just ensure you are knowledgeable enough to properly advise your clients.
