This house would stop Google from taking over the world.

Google did not ask publishers permission before posting pages for its library project, Googlebooks. The whole publishing industry is threatened in the same way the music industry was threatened by Napster.
"The fear factor first came into public view over copyright issues, when Google began digitizing millions of books at various libraries starting in 2004. The company built scanning machines from scratch and hired workers to run them. Still in test mode, Google Book Search, which includes both the library project and separate agreements with publishers, lets users search for words within the books it plans to scan. Searches bring up a table of contents and snippets containing the words; publishers can agree to make sample pages available.The problem was, Google chose not to ask publishers' permission before it launched the library project, claiming that copying books to provide snippets of text in searches was fair use under copyright law. And it took few pains to ease publishers' concerns: Why would people buy a whole book when all they need is a few paragraphs from a simple search? If that's what potential buyers end up doing, Google destroys their whole economic model. As a result, the Authors Guild and a group of publishers, including BusinessWeek owner The McGraw-Hill Companies (MHP ), each filed lawsuits in 2005 against the library scanning project, charging that it violates their copyright."[[http://www.businessweek.com/magazine/content/07_15/b4029001.htm]]
Libraries do not give books or pages of books out for free, and/or without publisher permissions.

Amazon does the same thing, the only difference is that Google didn't 'originally' take publisher permissions. Google does not display entire books but sample chapters, and this is a kind of free advertising.
