"Starting today, we're enabling people everywhere to find and read full text legal opinions from U.S. federal and state district, appellate and supreme courts using Google Scholar."A quick search using the terms "copyright infringement fair use" gave me access to several of the major opinions including: Sony v. Universal; Harper & Row; Campbell v. Acuff-Rose; and A&M v. Napster. The amazing thing is that Google Scholar even utilizes links to citations. For example, Google Scholar provided links to 2,704 court cases and legal papers that cited Campbell v. Acuff-Rose.
What Google Scholar does is bring relatively easy access to court cases to the masses for free. However, at present it does not flag negative authority; a must for most lawyers. Google Scholar appears to be a great free source to quickly nab a specific published case. Westlaw and Lexis Nexis just lost a lot of business.
