Google has upped the ante with an upgrade to Google Book Search that allows users to search digitized book results as well as records for millions of other books that still just exist in the analog world. When viewed, the new added book records have a summary, reviews and links to buy the book or find it in a library nearby since previews of the text are unavailable. "We're doing this because we want to offer users the most comprehensive book search in the world - whether it's a book you can read online now, preview samples, see a few snippets, or just read what others have written about the book. We're still very busy digitizing millions more books, but want to make as much discoverable as possible today."
