U.S. Circuit Judge Denny Chin said the creation of a universal library would benefit many but would "simply go too far."
He said the settlement of the class-action lawsuit challenging the right of Google to scan books and display snippets for online searching would "grant Google significant rights to exploit entire books, without permission of the copyright owners."
Chin said the deal gives Goggle "a significant advantage over competitors."
He said it would be "rewarding it for engaging in wholesale copying of copyrighted works without permission, while releasing claims well beyond those presented in the case."
