I have done legal research before, but mostly on criminal law and civil claims/torts.
Tax law is a whole nother beast. First of all, most of it is not actually laws at all, but regulations. And it is a ginormous mass of stuff which is particularly technical and hard to parse.
If I wanted to research particular topics in tax law, what would be the right approach. Are there specific types of official guides that can make the problem easier, sort of a Cliff Notes of tax law?
