Not so long ago, to gain access to information about the law, one had to go to a specialised law library, to a courthouse, or to a legislature. In many parts of Europe and the United States (US), today, the primary law is published online. If you want to know about legislation recently passed in the US Congress, the answer is a Google search away. The same is true of a new opinion handed down from the Supreme Court. Publication tends to be prompt; access is nearly instantaneous and free.
