I do the same thing with articles I've had in The Wall Street Journal and Forbes.
...usually the direct-link to their site for the original article covers most bases.
There should be a statement about your rights for usage after an article or somewhere on their site about it. They know you're going to want to promote the article, though and are usually accommodating as long as you direct-link.
These things are tricky sometimes.I went to Kinko's onetime and tried to make color copies of the article to frame , and they wouldn't let me make any copies at all
