The U. S. Department of Justice extended its concerns Thursday over a revised legal settlement that Google Inc. struck with authors and publishers to make millions of books available online, pointing that there were still numerous legal problems with the amended agreement even after recent revisions.

The department cited the new agreement was improved version of the earlier one. Although, it revealed the alterations made were not enough to tranquilize concerns that the deal would fetch Google a win over millions of orphan works.

The department also voiced several objections to the original settlement, saying it was overly broad and raised antitrust and copyright concerns.

It also claimed Thursday that a "properly structured" agreement could offer important benefits to society; however, it revealed that Google, the Authors Guild and the Association of American Publishers were in a bid to reach too broadly with their proposed class-action settlement.

On the other hand the parties revealed the settlement would cause a significant expansion in public access to digital books and would pose as a new source of revenue for authors and publishers.

Critics of the deal, including Amazon. com Inc. and Microsoft Corp., have posted comments with Judge Chin gainsaying that the settlement would give Google a edge in digital books.
