Today, the Mountain View company Google released a major update for its Book Search technology, aiming to make it more powerful than ever. Every once in a while, the search giant signs deals with libraries or universities from all around the world to digitize their content and include them in Book Search. Today, Google announced an agreement with the University of Lausanne to digitize an impressive amount of content currently stored in their library.

"Today on the Inside Book Search blog comes the news that we're now including results for many more books -- including ones that we have not digitized through our partnerships with publishers and libraries. We've added metadata records to the Google Book Search index, which means you can now search across a much more comprehensive index of books and find places to buy or borrow the books that interest you," Bethany Poole, Product Marketing Manager, said today.

Book Search evolved a lot and this is obvious because it includes a lot of new features compared to the basic product that was released a long time ago. For example, you're now able to buy a certain book or even borrow it straight from the search results or by using the links provided by Google. The "About this book" button is even more powerful and allows you to read reviews, book references, users' opinions and a lot of new information concerning a certain publication.

This search engine is obviously an innovative search technology that is currently the only product in its category without any competitive rival to challenge it. However, the parent company Google is continuously working on the search engine and improves it periodically even if there is no competition for it. Every once in a while, the search giant signs deals with libraries and universities, trying to conquer the world with agreements.
