Please submit the book's ISBN 13 in the window below and hit the little magnifying glass icon. The ISBN 13 must be from Google Books and only Google Books. Here's a link to Google Books. The reason the ISBN 13 must be from Google Books and only Google Books is that we use the Google Books database to pull the bibliographic metadata on the book into the NBN database (so you don't have to type it).
Search for the book in Google Books. When Google Books finds it, it will show you a big pop up of the book's cover. This is annoying. You can close the book cover image by clicking the big "X" in the upper right hand corner of the window. Once you do that, you'll see the ISBN 13 in the detail for the book. Copy it and paste it into the window without any dashes. Then hit the magnifying glass icon.
If you cannot find the book in Google Books, contact me (email@example.com) and I'll add the title by hand.
