December 2004: Google signaled an extension to its Google Print initiative known as the Google Print Library Project. Google announced partnerships with several high-profile university and public libraries, including the University of Michigan, Harvard (Harvard University Library), Stanford (Green Library), Oxford (Bodleian Library), and the New York Public Library. According to press releases and university librarians, Google planned to digitize and make available through its Google Books service approximately 15 million volumes within a decade. The announcement soon triggered controversy, as publisher and author associations challenged Google's plans to digitize, not just books in the public domain, but also titles still under copyright.
