BetaNews is reporting that the University of California and Google today struck a deal to add all public domain books in the University's collection to Google's ever-growing book-scanning project.  This expansion, pulling in books from over 100 libraries in the state-wide University system, is the largest Google has seen yet.

The Google Book Search project is perhaps one of the most controversial of all of the search and advertising company's various projects, drawing criticism and claims of copyright infringement from both the Association of American Publishers and the Author's Guild.  This recent growth has drawn ire from the Association of Learned and Professional Society Publishers.

Google Book Search is working to scan all public domain works and make the readily available online, and to take copyrighted titles, scan their title, author, a few lines of text and provide the user with information on where to purchase the work.  Google is taking a page from the long-running Project Gutenberg, whose efforts to scan into raw text classics of literature that have fallen into the public domain has been going since 1971.
