The thing that strikes me about all this craziness over Google Book Search is that Google did an extraordinary thing: they made significant progress toward scanning every book ever printed. With great effort (and risk) comes great reward. It would be a huge cost, but I don't see why another company doesn't try to do the same thing.
The monopoly doesn't exist because Google is trying to force other people out; it exists because no other company is willing to take the expense/risk to do it themselves.
Amazon, Yahoo, and Microsoft all come to mind. Yahoo and Microsoft for relevance to search, and Amazon as a bookseller. They're all big enough and technically competent enough to do it, in my opinion.
Indeed, But Microsoft is seen in... slightly less favorable light than Google. Amazon's position on the other hand could be a drawback, not an advantage. Such step could have made angry its providers.
