Google Play Books is not books.google.com, which has all the public domain books they got from public libraries.
The specific functionality they took away is devastating to regular users like me. When searching, results would show if a book was already in your library. You could also add it to a shelf from the search result itself. Now the search results lack that info and you must click on each result to see if it's one you already saw. This is sheer hell for discovering books that weren't there between searches.
