Because books published before 1923 are in the public domain, I am able to view them easily.

But the vast majority of books ever written are not accessible to anyone except the most tenacious researchers at premier academic libraries. Books written after 1923 quickly disappear into a literary black hole. With rare exceptions, one can buy them only for the small number of years they are in print. After that, they are found only in a vanishing number of libraries and used book stores. As the years pass, contracts get lost and forgotten, authors and publishers disappear, the rights holders become impossible to track down.

Because books are such an important part of the world's collective knowledge and cultural heritage, Larry Page, the co-founder of Google, first proposed that we digitize all books a decade ago, when we were a fledgling startup. At the time, it was viewed as so ambitious and challenging a project that we were unable to attract anyone to work on it. But five years later, in 2004, Google Books (then called Google Print) was born, allowing users to search hundreds of thousands of books. Today, they number over 10 million and counting.

The next year we were sued by the Authors Guild and the Association of American Publishers over the project. While we have had disagreements, we have a common goal � to unlock the wisdom held in the enormous number of out-of-print books, while fairly compensating the rights holders. As a result, we were able to work together to devise a settlement that accomplishes our shared vision. While this settlement is a win-win for authors, publishers and Google, the real winners are the readers who will now have access to a greatly expanded world of books.

For those books whose rights holders have not yet come forward, reasonable default pricing and access policies are assumed. This allows access to the many orphan works whose owners have not yet been found and accumulates revenue for the rights holders, giving them an incentive to step forward.
