Today online sources make research a bit simpler but finding the laws, regulations, and case law is only the beginning. Interpreting the laws, and regulations requires a legal mind and a whole lot of experience in this highly specialized field.
Today there are a lot of online resources, many of which we have referenced from time to time. Online resources certainly make research easier and if you are inclined to perform your own legal research, there is a great free resource at the GAO.

GAO publishes a new edition every few years (currently its on edition 4) which represents a complete update and involves hundreds of hours of research and verification on the accuracy of every cited work.
