When you import PDF files to your page, you may enter the edit page to create a media-rich book thorough adding as much medias (video, SWF Flash, YOUTUBE video, image, sounds) as you want. In addition to about-mentioned Medias, you also can add new buttons or links to call more actions (such as javascript) .
