Today, Google is expected to announce relationships with five major libraries, including the University of Michigan, Oxford University and the New York Public Library, to create digital copies of some books so that they may be searchable using Google. Also on Tuesday, the company will begin sampling some works already scanned for Google Print, the company’s searchable index of books that it formally unveiled in October. It will take some time before all the information is available, but over the next year you will be able to take advantage of the increased database.
