Each article's view pages are unique? Or are they all one page with uniquely propagated iframes? If it's one page, then add it to your robots.txt file as a disallowed page.
Otherwise yes you can no-index
OR you can add a rel="nofollow" to the links which might be a good idea anyway. Of course if the page is linked from anywhere else it could be indexed.
Or you could send them all to a unique directory and have that particular directory removed in the robots file. This would pertain if each article was given a unique page. Just have them go to url.com/article/view/thisarticle.html and disallow the view/ directory.
Hope this helps.
