The Authors Guild and a Lincoln biographer, a children's book author, and a former Poet Laureate of the United States filed a class action suit today in federal court in Manhattan against Google over its unauthorized scanning and copying of books through its Google Library program. The suit alleges that Google is engaging in massive copyright infringement at the expense of the rights of individual writers. Through its Library program, Google is reproducing works still under the protection of copyright as well as public domain works from the collection of the University of Michigan's library. Google has agreements with four academic libraries -- those of Stanford, Harvard, Oxford and the University of Michigan -- and with the New York Public Library to create digital copies of substantial parts of their collections and to make those collections available for searching online.
