Regular readers know how much I love Google, BUT, when it comes to in depth research, Google is barely a beginning. For excellent resources online on various legal areas - e.g. labor, securities, tax - look at the BNA databases on the Law Library's Research Databases page. For non-legal research, look at the Subject listing of databases available from Axinn.
