Author attribution for books used in promotional video?

I work at a University Library in Canada, we've recently produced a promotional video for a book scanner. In the video, we demonstrate the use of the book scanner using a random book off the shelf, but the focus is always on the scanner, never on the pages of the book (though there are some shots where you can see pictures, and at least one where you can read a title on the page). One of the Librarians is under the impression that we need to cite the book and give attribution to the author. Originally we thought we could probably pass this off as incidental use, but according to the Librarian it's not, because we deliberately used that book as a prop. I've never heard of attribution being given to authors of books used as props, is this really necessary?
