eldavojohn writes "Mercury News is running a story reporting that Google has filed subpoenas with Microsoft and Yahoo, in relation to their legal battles with publishers and authors. Google faces charges of massive copyright infringement surrounding its online book project. The company claims that Microsoft and Yahoo have taken the exact same steps in acquiring print-related rights. Google therefore wants to show that 'everyone is doing it.'" From the article: "McGraw-Hill Cos. and the Authors Guild, along with other publishers and authors, contend that a Google project to digitize the libraries of four major U.S. universities, as well as portions of the New York Public Library and Oxford University's libraries, ignores the rights of copyright holders in favor of Google's economic self-interest ... Is the library of the future going to be open? Or will it be controlled by a couple of big corporate players?"
