MOUNTAIN VIEW, Calif. (AP) - Google and U.S. publishers have settled a longstanding dispute over Google's book-scanning project. A lawsuit filed by authors remains, though, leaving the project in question.

The Association of American Publishers and Google Inc. announced their settlement on Thursday.

Google already has scanned more than 20 million books. Publishers and authors sued, saying the project violated their copyrights. Authors' and publishers' groups had settled with Google before, but a federal judge tossed the deal following objections. One point of contention was the fact that books were included unless Google was informed that an author or publisher objected.

Google and the publishers say the new settlement won't require court approval because it involves only parties to the litigation. Publishers will get to choose which books are included.
