The US Supreme Court used to have all cases going back to the 1700's easily available. These were separated by categories such as search and seizure, civil rights etc. This is no longer true. The format is now such that you must know the case you are looking for to find anything. This has made it very difficult to discover useful case law. I used to spend hours going through case history to find gems which are helpful to the average guy. Now I'll have to find another source.
