There are already tons of tweets and posts about Google Scholar's new case law content, so I'm not going to reinvent the wheel. Yes, Google Scholar has case law now!
Google's official announcement;
Review of case law on Google Scholar over at Internet for Lawyers;
Librarian reviews over at Resource Shelf;
More librarian reviews at the Law Librarian Blog;
Another lawyer review over at Ernie the Attorney.
And just to add to all of the excitement, Legal Research Plus posted this week about a new ABA web resource that furnishes "prompt, accurate, unbiased information about newsworthy and legally significant cases pending in and decided by the Federal Courts of Appeals."
It's been a fabulous week for free legal information on the web!
