The Google Book Search "library" will be composed of both out-of-print and inprint books. Out-ofprint books scanned by Google from academic libraries are included in the database by default, although authors or publishers may request that specific books be removed.

One of the first tasks Google will have is to help determine what is in print and what is out of print, by discovering which books are commercially available. Out-of-print books are the central focus of the project. The goal was not to displace the traditional market for in-print books, but to create a new market for out-ofprint books. Many books that were unavailable to the general public, and thus earned nothing for their authors, will get a second chance as a result of the settlement. Authors can easily opt out of the system through the Book Rights Registry. Authors can contact the Registry and say, for example, that they want some of their titles available and others unavailable—and can change this later on. All licensing revenues go initially to Google, which keeps its 37% share and forwards the remaining 63% to the Book Rights Registry. The Registry then forwards the appropriate amount to rightsholders, keeping an administrative fee. Google also passes on usage data, which determines how the Registry distributes payments. The revenue split between authors and publishers includes several different categories. For out-of-print books, there are three possibilities:
