Hi Diane - I'm not quite sure whether these articles have links pointing back to your site or not but one popular way of promoting them would be to have a section on your homepage where you can list the various publications that your site has appeared in.
If you wanted to, you could include a link to the specific article so that visitors to the site can read what other people have written for themselves. However, the main benefit of this would be to increase both the brand and trustworthiness of your own site.
It doesn't have to be particularly huge, but even a small box down one side of your site listing the logos of the various publications you've appeared in can increase conversion fairly impressively.
Hope that helps!
