It was up and down for Google last week.

On the downside, the United States Department of Justice, in a brief filed in federal court, strongly criticized the search giant’s tentative settlement of a class action suit launched over its plan to scan and post millions of books online. The DOJ’s objections were serious enough that Google and the other parties to the deal asked the judge overseeing it for more time to address those complaints. (On Thursday, Judge Denny Chin of the U.S. trial court in Manhattan granted the motion to delay.)
