Judge Denny Chin issued an order Wednesday in Manhattan federal court. In May, he ruled class action was "more efficient and effective" than requiring thousands of authors to sue individually.
The Mountain View-Calif.-based Google appealed the ruling and asked to delay all proceedings until the appeals court rules. The judge said a delay was unwarranted, especially since it would delay the case for a year or more.
Google already has scanned more than 20 million books for the project. The Authors Guild had requested class certification.
Lawyers for Google did not immediately respond to a message for comment.
