How good is the scanning?
For the vast majority of books in the Google Book Search index, the quality of the scanned pages is extremely good, but that doesn’t mean there’s not more work to be done. Google has developed technology to scan millions of books at a scale and pace previously unimaginable. The company is continually improving the technology and methods used to scan book pages and to process the images into format viewed by users. As the project addresses the vast majority of pressing preservation problems facing larger libraries, it will allow us to focus attention and resources on works that require special handling.
