Managing external links from my Drupal site

I'm building a site of encyclopedia like articles and each article should have a section which can contain reference links to external websites, and have been looking for a good way to manage those links. I want to maintain those links from a central location. What I came up with was as follows:

install CCK Redirection module, create an External Reference content type which contains a Title and a redirection URL.
install CCK NODE Reference module, add a node reference field to my Article type which is restricted to my External Reference content type, set the field to allow more than one item.

That option seems to work, allows for Role based control of these external links, and even plays well with Internationalization.

My question is does anyone have a suggestion for a better way to do this? I think this approach is pretty good, but want to see if there is something better before I go ahead with it.
