The Authors Guild and Association of American Publishers separately sued Google in 2005 for its book project, citing "massive copyright infringement." Google countered that its project represented a fair use and is the digital age equivalent of a card catalog with every word in the publication indexed. The lawsuits were consolidated, and eventually a settlement was proposed. The settlement received significant criticism on a wide variety of grounds, including antitrust, privacy, and inadequacy of the proposed classes of authors and publishers. The settlement was eventually rejected, and the publishers settled with Google soon after. The Authors Guild continued its case, and in 2011 their proposed class was certified. Google appealed that decision, with a number of amici asserting the inadequacy of the class, and the Second Circuit rejected the class certification in July 2013, remanding the case to the District Court for consideration of Google's fair use defense.
