Google zigged again, cutting across the zags of the search engine industry to announce today that it was embarking on a major push to digitize parts of some of the world's greatest libraries, according to the New York Times. In news that messily leaked out from library owners, Google plans tout its agreements with Harvard University, Stanford University, University of Michigan, Oxford University and the New York Public Library to digitize each page of more than 15 million books and special collections documents. Google will offer the material up to its search index online and run advertising against the results. The libraries will have their digitization efforts funded. Books under copyright will be searchable, but the full text will not be available online, much like Google does with its Google Print product, which digitizes new book titles from publishers HarperCollins, Penguine, Houghton Mifflin and Scholastic.
