Das in Google Books integrierte «Talk to Books» liefert Zitate, die auf die eigenen Fragen antworten (via Archivalia und chromeunboxed.com):
«What I mean is that you type a question or a statement into the search bar (obviously, it’s Google!) and in return, you’ll get quotes from inside of books that seemingly answer your questions or pertain to your sentence. It almost brings books to life – it’s kind of spooky. The utility here is that you can find books relevant to your interests or needs much easier than searching Google’s standard engine and getting a bunch of returned links or related websites.»
