How could I use quads to make a book?

I've been told that quads are a good way to create a 3D book. The game I am creating is first-person, and I would like the player to be able to open a book whenever they like. They could flip pages, and look through the information given. In the future I will worry about adding words to the pages, and some other things. I was inspired by this gameplay, about 53 seconds into the video: http://www.youtube.com/watch?v=YxDFGjz9s8E The only problem is I don't know what they are, and how to use them. To put it simply, how would I create the covers and pages? I would be grateful if someone could talk me through it! Thanks.
