Copyright holders - located in the US and internationally - may have their books included in this agreement. As part of a worldwide notice program, the settlement administrator will be reaching out to authors and publishers around the world to tell them about their rights under the settlement, which include the right not to have the settlement apply to them and the ability to register with the Book Rights Registry to control and profit from online access to their books.
However, because this agreement is the result of a US lawsuit, it only affects the Book Search experience for users accessing the site in the US. Outside the United States, the users’ experience with Google Book Search will be unchanged, unless the offering of such products and services is authorized by the rightsholder of a book.
