The Google Books project is an undertaking by Google to digitise millions of books from around the world (20 million scanned thus far). Google has developed partnerships with a number of major international libraries and mainstream publishers in order to secure content. The publishers provide content on the provision that only a proportion of the work is accessible and a purchase option is provided. Google has however; run into legal issues due to the fact that the company has digitised in-copyright works without first seeking permission from the copyright holder. A settlement was reached in 2009 which offered rights-holders a percentage of the revenue, or the choice to opt out of the scheme; e.g. remove their works. The original settlement also provided US public Libraries with unrestricted on-site access to books which are no longer commercially available (p58 22). In 2011 the settlement was rejected and the parties are back in court.
