How Google Books works
Finding books with Google Books is as easy as finding websites with Google Web Search; just enter the keyword or phrase you're looking for into the Google Books box. For example, when you search for [rock climbing] or for a phrase like [one small step for man], we'll find all the books whose contents match your search terms.
Click on a book title and you'll see basic info about the book just like you'd see in a card catalog. You might also see a few snippets — sentences of your search term in context. If a publisher or author has given us permission, you'll see a full page and be able to browse within the book to see more pages. If the book is out of copyright, you'll see a full page and you can page forward or back to see the full book. Clicking on Search within this book allows you to perform more searches within the book you've selected.
You can click on the Buy eBook button to buy a book from the Google Play store. In many cases, you can also click Find this book in a library to find a local library where you can borrow it. If the book is available as a Google eBook, you'll also see a buy button for purchasing the digital edition.
