The 2004-2005 Chambers USA Guide to America’s Leading Business Lawyers, the only legal directory to rank law firms and individual lawyers, was released today on the Web. The guide, which is published by Chambers and Partners, the London-based publisher of Chambers Global and Chambers UK Leading Lawyers, investigates the top firms and lawyers for each state in over 20 areas of commercial law. It says that its detailed research distinguishes it from any other attorney listing in the nation.
