Google Books was the company's first moonshot. But 15 years later, the project is stuck in low-Earth orbit
, argues an article on Backchannel. From the article: When Google Books started almost 15 years ago, it also seemed impossibly ambitious: An upstart tech company that had just tamed and organized the vast informational jungle of the web would now extend the reach of its search box into the offline world. By scanning millions of printed books from the libraries with which it partnered, it would import the entire body of pre-internet writing into its database. [...] Two things happened to Google Books on the way from moonshot vision to mundane reality. Soon after launch, it quickly fell from the idealistic ether into a legal bog, as authors fought Google's right to index copyrighted works and publishers maneuvered to protect their industry from being Napsterized. A decade-long legal battle followed -- one that finally ended last year, when the US Supreme Court turned down an appeal by the Authors Guild and definitively lifted the legal cloud that had so long hovered over Google's book-related ambitions. But in that time, another change had come over Google Books, one that's not all that unusual for institutions and people who get caught up in decade-long legal battles: It lost its drive and ambition.
Google stopped updating Books blog in 2012, and folded it into the main Google Search blog. The author reports that Google still has people working on Book Search, and they are adding new books, but the pace is rather slower.
