For some articles, there will be a direct link that says View Article or Get PDF. That link finds the "most stable" link to the article.
For all electronic resources, there will be a link that says "Available - View Online" which will list the database links and you can choose one. Most will have one link but sometimes the library has access to an article in more than one database, or the Vendor (like Gale) provides access in more than one of their databases, in that instance just choose a link.
