Wow is all we can say at Traverse Internet Law. Google has just launched a robust index and search engine for legal decisions in the US. You can search by jurisdiction, subject, etc. and it will return results by relevance. It's called Google Scholar.
Law firms have paid for research tools that generate this information over the years. Now everyone can research in a quality way the court decisions and other legal commentaries on the issue you face in the locality you live. This is groundbreaking and, as Googlers state on their blog, a real benefit to the everday man and woman on the street who simply did not have the visibility into the volumes upon volumes of caselaw buried in law libraries around the country.
You should too.
